Description
Technical field
The invention belongs to Metallic Materials and Heat Treatment technical field, is related to a kind of magnesium alloy materials and magnesium alloy materials
Manufacture method.
Background technology
With the development of science and technology, strided forward now in the design of various products both facing to the target of light weight, weight environmental protection, because
This, the exploitation and characteristic selection for product material are upper, it is necessary to make considerable degree of consideration.Wherein, answering and with alloy material
It is the most extensive with scope, herein by taking magnesium alloy materials as an example, magnesium metal be have in practicality metal measure light, high damping capacity and
The advantages that recyclability is superior, and can with other metallic elements with reference to and formed with high strength-weight ratio and good resistance to
The magnesium alloy materials of impact and wearability.
By taking AZ80 magnesium alloys as an example, AZ80 magnesium alloys are the forging type magnesium alloys having been commercialized at present, because it has height
Intensity and it is cheap the advantages that, therefore, both at home and abroad whether industrial circle or academia all throw oneself into research and development AZ80 forging
The related process and application technology of type magnesium alloy.However, AZ80 magnesium alloys have still had subproblem, for example, ductility is not
Foot, cause the degree of difficulty increase of forging, thermal conductivity and conductance are bad, weldability is bad, too high (1.81 g/often stand of density
Fang Gongfen (g/cm3)), cause quality of magnesium alloy is overweight to wait limitation.
The content of the invention
Ductility of the invention for existing magnesium alloy is insufficient, weldability is bad and the too high caused quality mistake of density
The problems such as weight, the present invention provides a kind of magnesium alloy and its manufacture method, by changing its smelting process so that its quality is changed
It is kind, reach the purpose for improving its quality.
The technical scheme is that：
A kind of magnesium alloy, it is characterised in that be made up of following element：
Magnesium elements, its percentage by weight are the 85% of alloy total composition；
Elemental lithium, its percentage by weight are the 12% of alloy total composition；
Zn-ef ficiency, its percentage by weight are the 2% of alloy total composition；
Manganese element, its percentage by weight are the 0.3% of alloy total composition；
Element silicon, its percentage by weight are the 0.2% of alloy total composition.
A kind of manufacture method of magnesium alloy, it is characterised in that comprise the following steps：
(1) alloy material for including the magnesium elements and the element silicon is inserted in a crucible of a vacuum induction melting furnace；
(2) vacuum induction melting furnace is subjected to vacuumize process；
(3) crucible of vacuum induction melting furnace is heated, the alloy material is melted；
(4) molten alloy is poured into the Sheng bucket containing inert gas shielding and a preset elemental lithium, contains this to be melt into
The alloy of elemental lithium；
(5) molten alloy containing the elemental lithium is poured into a mold and cools down ingot, and formed in a manner of squeezing forging, with shape
Into a magnesium Li-Si alloy material；
(6) magnesium elements and the element silicon are combined reaction, to separate out a magnesium silicide in the magnesium Li-Si alloy material internal
Compound.
Beneficial effects of the present invention are：A kind of magnesium alloy proposed by the present invention and its manufacture method, component is novel, makes
Cheng Heli is clear, and fusion process control is easy；The present invention, it is in including in the alloy soup of magnesium elements, aluminium element and element silicon
Add elemental lithium so that alloy melt soup in solidification ingot and squeeze be swaged into as magnesium lithium alloy material after, reduce density of material it is same
When, its global tissue uniform and delicate, can be reacted plus elemental lithium and aluminium element and separate out aluminium lithium phase, or magnesium elements and element silicon it is anti-
Silication magnesium compound should be separated out, its ductility is very damaged so as to the rigid and nothing for improving magnesium alloy.
Embodiment
The invention will be further described below：
A kind of magnesium alloy, it is made up of following element：
Magnesium elements, its percentage by weight are the 85% of alloy total composition；
Elemental lithium, its percentage by weight are the 12% of alloy total composition；
Zn-ef ficiency, its percentage by weight are the 2% of alloy total composition；
Manganese element, its percentage by weight are the 0.3% of alloy total composition；
Element silicon, its percentage by weight are the 0.2% of alloy total composition.
A kind of manufacture method of magnesium alloy, comprises the following steps：
(1) alloy material for including the magnesium elements and the element silicon is inserted in a crucible of a vacuum induction melting furnace；
(2) vacuum induction melting furnace is subjected to vacuumize process；
(3) crucible of vacuum induction melting furnace is heated, the alloy material is melted；
(4) molten alloy is poured into the Sheng bucket containing inert gas shielding and a preset elemental lithium, contains this to be melt into
The alloy of elemental lithium；
(5) molten alloy containing the elemental lithium is poured into a mold and cools down ingot, and formed in a manner of squeezing forging, with shape
Into a magnesium Li-Si alloy material；
(6) magnesium elements and the element silicon are combined reaction, to separate out a magnesium silicide in the magnesium Li-Si alloy material internal
Compound.
Instant component is novel, and manufacturing process is rationally clear, and fusion process control is easy；The present invention, it is in including magnesium
Add elemental lithium in the alloy soup of element, aluminium element and element silicon so that alloy melt soup in solidification ingot and squeeze be swaged into as magnesium lithium
After alloy material, while density of material is reduced, its global tissue uniform and delicate, analysis can be reacted plus elemental lithium and aluminium element
Go out aluminium lithium phase, or magnesium elements and element silicon reaction separate out silication magnesium compound, rigid and nothing so as to improving magnesium alloy
Very damage its ductility.
