Description
Technical field
The present invention relates to the titanium so that driver (driver) is used by the pole face blank of main golf clubs close
Gold.
Background technology
In recent years, along with golf clubs can not have spring effect (Spring Like Effect=SLE) this
Rebound coefficient regulation (SLE rule) is imported into, and the kind for the titanium alloy blank of Golf club face purposes changes significantly.?
Carry out before rebound coefficient (recovery coefficient) regulation, low Young's modulus (Young ' s modulus), can be readily derived high
Ballistic properties, high intensity and excellent in te pins of durability, based on the beta titanium alloy of Ti-15%V-3%Cr-3%Sn-3%Al alloy
It it is main flow.But, along with the importing of rebound coefficient regulation, in order to use the beta titanium alloy of low Young's modulus, and reduce bounce-back
Coefficient meets regulation, only thickens pole face thickness of slab to the method improving the rigidity of pole face.When using this approach, by a large amount of
In the case of the beta titanium alloy of the alloying element of the high price containing V, Mo etc. is applied to pole face blank, cost improves can not be kept away
Exempt from.And, beta titanium alloy, compared with other titanium alloy, proportion is also big, and along with thickening thickness of slab, pole face becomes weight.Such one
Coming, pole face uses the volume of the glof club head of beta titanium alloy to be limited, sweet spot (sweet-spot) phase during impact ball
Diminish over the ground, therefore there is also the most unworkable problem.Due to such reason, beta titanium alloy starts
Becoming is not the main flow of Golf club face blank.
Compared with beta titanium alloy, the alpha and beta type titan alloy that Young's modulus is high, the most just become as driver pole face blank
For main flow.By using the alpha and beta type titan alloy that Young's modulus is high, even if thinning pole face, rebound coefficient is also difficult to uprise, with β type
Titanium alloy is compared, and is improved by the thickness of slab degree of freedom of (meeting) rebound coefficient regulation.It addition, compared with beta titanium alloy, proportion
Little, even identical quality, it is also possible to increase the capacity of club head.And, compared with β type alloy, the alloy unit of high price
The content of element is low, and therefore blank cost is the lowest, has these a lot of advantage above-mentioned.As this alpha and beta type titan alloy, Ti-6%
Al-4%V is representational alloy, but in addition, it be also possible to use such as Ti-5%Al-1%Fe, Ti-4.5%Al-3%V-
2%Fe-2%Mo, Ti-4.5%Al-2%Mo-1.6%V-0.5%Fe-0.3%Si-0.03%C, Ti-6%Al-6%V-2%
Sn, Ti-6%Al-2%Sn-4%Zr-6%Mo, Ti-8%Al-1%Mo-1%V, Ti-6%Al-1%Fe etc..
If using these alloys, even if then making face thickness thinner than beta titanium alloy pole face, also meet rebound coefficient rule
System, and by using the titanium alloy of suitable strength-ductility scope, it is also possible to required for Golf club face is given
Durability.Even if in the case of thinning face thickness also requires that the senior golf clubs of high-durability, change pole face shape
And/or structure can control the pole goods etc. of ballistic properties, preferably there is the Young's modulus of more than 120GPa, more than 950MPa
Tensile strength, the elongation at break of more than 15%.The sheet products etc. that degree of finish is few when pole face forms, preferentially at plate
A direction in face has the Young's modulus of more than 135GPa, the tensile strength of more than 1100MPa, the fracture of more than 7% are stretched
Long rate.In these cases, about Young's modulus, in order to by rebound coefficient regulation, and, about tensile strength and extension
Property, in order to obtain good durability, preferentially meet above-mentioned value.But, usually, type alpha+beta alloy, processability is the worst
It is good, even if thinning thickness of slab also has high-durability and meets the high intensity of rebound coefficient regulation, high Young's modulus and good
The type alpha+beta alloy that hot-workability has both is limited.
Such as, as the Ti-6%Al-4%V alloy of the most general type alpha+beta alloy, have sufficiently as pole face blank
Intensity, Young's modulus, be widely used as Golf club face alloy.But, this alloy contain 6% at high temperature
, there is the problem that hot-workability is bad in the Al that lower display solution strengthening ability, deformation drag when making hot-working increase, it addition,
, there is the problem that blank cost is higher in the β phase stabilizing element V of the high price containing 4%.
Patent documentation 1 proposes a kind of has high specific strength and low cost in the same manner as Ti-6%Al-4%V alloy
Alloy.This alloy be by as β stabilizing element by the high price of V and Mo etc., than heavy element substitution for cheap, β is steady
Surely change the high Fe of ability, and more add the α phase stabilizing element Al of light specific gravity, seek high specific strength and low cost
Type alpha+beta alloy.But, this alloy contains the Al of 5.5～7%, has and is difficult to hot worked difficult point.Particularly to reduce towards bar
If the processing cost of face blank, it is desirable to so that only pole face shape just can be processed into by light compressing and grinding step
Slab products supplies, but this alloy is due to high thermal deformation resistance, it is difficult to appearance becomes slab products.Particularly when hot rolling, should
The suitable hot rolling temperature range of alloy is narrow, if temperature somewhat reduces than it, is easy for raw edges, there is product qualified rate
Low problem.
Patent documentation 2 proposes a kind of glof club head protecting high intensity and low bounce-back titanium alloy pole face.At structure
Become in the titanium alloy of pole face, it is stipulated that the content of Al and Fe, thus obtain high Young's modulus and tensile strength.Patent documentation
Be silent on the concrete manufacture method of this alloy in 2, but will in detail in the claims shown in Al and Fe containing not
If obtaining the tensile strength of 1200 described in claim～1600MPa under the alloy composition of evitable impurity, manufacture
Method is considerably defined.That is, the hot-working state of hot rolling, forging etc. alloy or use after hot-working or cold working
The alloy that the method carrying out making annealing treatment obtains, it is impossible to obtain such intensity.And then when heat or cold working product have been carried out
The goods of this strength range can not be obtained in the case of effect heat treatment.The most only in cold working to the highest working modulus
In the case of there is the probability obtained.But, in this case, though high intensity can be obtained, but plasticity and toughness significantly reduce.Using
In the golf clubs of the pole face of such state, if pole face once occurs fatigue cracking, then it can not be suppressed to extend.This
Sample, exists and cannot ensure the recent problem to the high-durability required by Golf club face.
It addition, patent documentation 3 proposes a kind of heat affected area durable in the glof club head comprise weld zone
Property high, the pole face titanium alloy of Young's modulus and intensity can be adjusted by heat treatment.It is characterized in that: added by appropriate
Al, Fe, O, N adjust intensity and make the fatigue properties of heat affected area improve, and by controlling ageing strengthening heat treatment etc.
Heat treatment condition controls Young's modulus.But, after patent documentation 3 proposes patent application, rebound coefficient regulation (SLE rule)
Be implemented, become an alloy that demand Young's modulus is high, described in claims of patent documentation 3 alloy form and
Under the conditions of heat treatment, the problem that there is the situation of the high Young's modulus also having the rebound coefficient regulation that is not being met.

Summary of the invention
It is an object of the invention to, solve above-mentioned problem, it is provided that there is high Young's modulus and strength-ductility balanced
Alpha and beta type titan alloy.
Inventor finds: as Al, O, N by adding solution strengthening α phase, and selects cheap as β stabilizing element
Fe, and suitably limit the addition of these elements, when making the β phase fraction under room temperature reduce, do not rely on cold working strengthening
Or ageing strengthening heat treatment just can have both high intensity and meet the high Young's modulus of rebound coefficient regulation.Send out simultaneously
Existing, elongation at break is the best, shows high strength-ductility balanced, obtains high durability.It addition, this type alpha+beta
Alloy, proportion is also light, is best suited for the blank of Golf club face purposes.And, and based on Ti-6%Al-4%V alloy
Other type alpha+beta alloy is compared, and is limited to relatively low by the content of the Al making hot-workability reduce, therefore rolling load during hot rolling

The present invention completes based on above-mentioned opinion, using content below as main points.
A kind of Golf club face titanium alloy, it is characterised in that in terms of quality %, comprise 4.7～the Al of 5.5%, 0.5
～the Fe of 1.4%, the N of less than 0.03% and [O] eq (oxygen equivalent) of being calculated by formula (1) meet 0.25～the O of 0.34%,
Surplus comprises Ti and inevitable impurity；There is high intensity, high Young's modulus.
[O] eq=[O]+2.77 [N] formula (1)
Here, [O] is oxygen concentration (quality %), [N] is nitrogen concentration (quality %).
In accordance with the invention it is possible to provide to have the high strength-ductility balanced and Young's modulus Gao Er as feature
Husband's face alpha and beta type titan alloy.
Detailed description of the invention
The present inventor is in order to solve above-mentioned problem and probe component element and the manufacture method material to titanium alloy
The result of the impact that characteristic causes, finds: by controlling Fe, Al, O, N addition, it is possible to possess to thin-walled property also even if manufacturing
Require the high strength-ductility balanced and high Young required by senior Golf club face blank of high-durability
Modulus, and there is the alpha and beta type titan alloy of good hot-workability.Particularly find: by there is strengthening by being solid-solution in α phase
The addition of O and N of effect is defined as suitable scope by [O] eq formula, it is possible to does not reduces ductility and guarantees as high-end
High intensity required by Golf club face and Young's modulus.And then, based on Al, add O, N and carry out the basis of complex intensifying α phase
Invention alloy, in the case of manufacturing slab products, by unidirectional hot rolling or cold rolling, causes the anisotropic texture of material significantly to send out
Reach, produce the Young's modulus of plate width as the direction vertical with rolling direction and strength ratio rolling direction increases
Material anisotropy.
In Golf club face, if Young's modulus and tensile strength realize desired value in the longitudinal direction of Golf club face
I.e. abundant.Therefore, as long as realizing Young's modulus and tensile strength at least one direction of plate.And, in sheet products
In, by carrying out unidirection rolling, for rolling width direction, it is capable of target about Young's modulus and tensile strength.That is, as
The longitudinal direction of Golf club face is taken as above-mentioned plate width by fruit, then can obtain required for Golf club face at one
High Young's modulus on direction (longitudinal direction of Golf club face) and tensile strength.
The present invention is to complete based on above opinion.The reason of the various addition element shown in the selection present invention described below
By and limit the reason of its addition scope.
Fe is addition element cheap among β phase stabilizing element, has the effect of strengthening β phase.Further, stable due to β
Change ability is high, also is able to the characteristic of β phase stabilisation than relatively low addition even therefore having.Obtain as golf
If intensity required for face, need to add the Fe of more than 0.5%.On the other hand, Fe is easy solidifying segregation in Ti, separately
Outward, if adding in large quantities, then the volume fraction of low with α phase phase specific Young's modulus β phase increases, the therefore Young of block (bulk)
Modulus reduces, and the Young's modulus of pole goods gets lower than 120GPa, Young in plate face direction of sheet products
Modulus gets lower than 135GPa, becomes difficulty as Golf club face by rebound coefficient regulation.Affect in view of these, will
The upper limit of the addition of Fe is set to 1.4%.Furthermore, in order to, while paying attention to strength characteristics, be dropped by Young's modulus effectively
Low caused rebound coefficient regulation, is preferably 0.7% as the lower limit of Fe addition, the upper limit is preferably 1.2%.
Al is the stabilizing element of titanium α phase, is to have high solution strengthening ability and cheap addition element.In order to pass through
With the compound interpolation of O, N described later, obtain being able to ensure that the required intensity water of durability as senior Golf club face
Flat, i.e. pole goods tensile strength is more than 950MPa, tensile strength is on a sheet products direction in plate face
More than 1100MPa, is set to 4.7% by the lower limit of addition.On the other hand, if adding Al, then deformation drag more than 5.5% ground
In uprising, ductility reduction, required ductility can not be reached in durability as Golf club face, and, because heat becomes
Form drag increases and causes the reduction of hot-workability.Therefore, the addition of Al needs to be set to less than 5.5%.
O and N, in the intermediate gap solid solution of α phase, has the effect of solution strengthening α phase at a temperature of near room temperature.Pass through
Compound interpolation with Al, it is possible to reach high intensity and high Young's modulus.They are on the other hand different from Al, do not make thermal deformation hinder
Power rises, therefore by adding O, N, it is possible to suppression Al addition.As described in patent documentation 3～5, from O and N to Ti
From the point of view of the similarity of the strengthening mechanism caused, O and N can be by [O] shown in above-mentioned formula (1) to the effect of the intensity under room temperature
Eq mono-free burial ground for the destitute represents.When adding [O] eq O, N less than 0.25%, it is impossible to stably obtain: as senior golf clubs
Face show sufficient durability, pole goods tensile strength be more than 950MPa, a sheet products direction in plate face
Upper tensile strength is the intensity of more than 1100MPa.It addition, when adding [O] eq more than O, N of the scope of 0.34%, intensity mistake
In uprising, ductility reduction, on a direction in the plate face of sheet products, elongation at break cannot ensure 7%.Therefore,
The lower limit of [O] eq represented by formula (1) is set to 0.25%, the upper limit is set to 0.34%.
In the case of slab products, the unidirectional heat stocking of the titanium alloy found in the present invention in the chemical composition ranges of regulation
Or Young's modulus E of the plate width of cold rolling material, in the range of above-mentioned [O] eq, according to formula (2), eq is proportional and increases to [O]
Add.This is because by the increase of α phase stabilizing element, the reason that the β phase making Young's modulus reduce reduces.By in the present invention
[O] eq scope add O, N, the Young's modulus of plate width can obtain the value of about 140GPa.
E=41.2 [O] eq+130.2 formula (2)
About N addition, exceed when the usual way using the titanium sponge using the N containing high concentration adds
0.030% N time, easily generate and be referred to as the not molten of LDI (low-density field trash: Low de nsity Inclusion) and be mingled with
Thing, the qualification rate step-down of goods, therefore using 0.030% as the upper limit.
Pole and slab etc. when the forming of pole face shape with bigger degree of finish, by controlling pole face shape
Can be by rebound coefficient suppression in the case of relatively low, by having mentioned component scope, it is possible to obtain the characteristic with excellence
Golf club face.There is the titanium alloy of the present invention of mentioned component scope, also possess the machinability that comparison is good, therefore
It is suitable as pole face blank.
On the other hand, in the forming to pole face shape, slight processing is only carried out, by pole face shape in manufacture
In the case of rebound coefficient is suppressed the sheet products that the leeway being relatively low is few, if making to be referred to as Transverse-texture
The texture of (horizontal texture) is flourishing, then tensile strength and the Young's modulus of plate width uprises, as Golf club face
It is preferred with blank.If Al, Fe, O to be limited in the composition range of the present invention, and it is heated to β monophase field or beta transformation point slightly
Lower section alpha+beta 2 phase region temperature carry out unidirectional hot rolling or and then the direction identical with hot rolling direction carry out unidirectional cold rolling after
Commonly used suitably under the conditions of anneal, then Transverse-texture is the most flourishing, the intensity of plate width and
Young's modulus uprises, therefore, it is possible to manufacture the sheet products most suitable as pole face blank.
When manufacturing this sheet bar, from hot rolling or cold rolling start to finish, only roll in one direction consistently
The reason of system can obtain the present invention as target and material anisotropy plate width side together to obtain expeditiously
To the Transverse-texture of high Young's modulus.So, by there is high Young's modulus and strength-ductility
The plate width of this titanium-alloy thin-plate of balance is configured to the longitudinal direction of Golf club face or close direction, it is possible to system
Make pole face that is corresponding with rebound coefficient regulation and that possess high durability.
