Description
Technical field
The invention belongs to field of welding material, be specifically related to a kind of Ti-Zr-Cu-Ni-Co-Mo amorphous brazing filler metal and preparation method thereof.
Background technology
TiAl base intermetallic compound alloy has that density is little (is about 3.8g/cm
3), the feature such as specific strength and elastic modelling quantity are high, mechanical behavior under high temperature and antioxygenic property excellence, is considered to a kind of high temperature structural material desirable, that have broad prospect of application.Yet the hard fragility of the essence of TiAl alloy makes it be difficult to carry out even machining of temperature-room type plasticity shaping, thereby limited the range of application of TiAl alloy.In order to expand and deepen the application of TiAI base alloy, solve connectivity problem and seem particularly important.At present, the method for attachment of TiAl alloy mainly contains melting, friction welding (FW), diffusion connection and soldering etc.When melting connects TiAl alloy, inevitably can crack and high residual thermal stress the extremely difficult high performance connector that obtains.Friction welding (FW) is connected because relevant device cost is higher with diffusion, and TiAl workpiece dimension and surface accuracy is required also higher, so that the application in the connection of TiAl alloy has been subject to significant limitation.Compare with other methods of attachment, soldering has the advantages such as the temperature of connection is low, residual stress is little, joint design is flexible, heat affecting is little, equipment cost is low, joint good connecting effect, thereby is considered to a kind of method that is comparatively applicable to connecting TiAl alloy.
The solder that soldering TiAl alloy is conventional mainly contains Ag base, Al base and Ti base alloy.While adopting Ag base solder brazing TiAl alloy, can obtain higher room temperature strength of joint.The people such as R.K.Shiue adopt Ag-Cu eutectic solder BAg-8 induction brazing Ti50Al50 in the article " Infrared brazing of TiAl intermetallic using BAg-8braze alloy " of delivering on the 51st phase < < Acta Materialia > > for 2003, the development of maximum shear strength of the joint obtaining through 950 ℃, insulation 60s soldering has reached 343MPa, once yet environment temperature surpasses 400 ℃, the shearing strength of joint sharply declines.And the antioxygenic property of Ag base solder brazing joint is also poor.Obviously, adopt Ag base solder brazing to be difficult to give full play to the hot properties of TiAl alloy.Although Al base solder brazing temperature is low, during soldering TiAl alloy, easily generate stable fragility Ti
3al interfacial reaction layer, and this conversion zone be difficult to adopt heat treated way to remove at postwelding, so that the non-constant of joint mechanical property.The people such as R.K.Shiue adopt pure Al and BAlSi-4 solder to carry out induction brazing to Ti50Al50 in the article " Infrared brazing of TiAl using Al-based braze alloys " of delivering on o. 11th < < Intermetallics > > for 2003, result shows, adopt the strength of joint of fine aluminium soldering TiAl extremely low, while adopting BAlSi-4 soldering, the development of maximum shear strength of joint is significantly improved, but also only has 86.2MPa.Ti base solder because of its main constituent element and mother metal TiAl alloy phase with, thereby there is good wetability during soldering, the joint of acquisition is in conjunction with firmly, room temperature and mechanical behavior under high temperature are excellent, and its soldered fitting corrosion resistance is good.The people such as S.J.Lee adopt the thick Ti-15Cu-15Ni foil of 50 μ m to carry out infrared induction soldering to Ti-48Al-2Nb-2Cr in the article " Infrared joining strength and interfacial microstructures of Ti-48Al-2Nb-2Cr intermetallics using Ti-15Cu-15Ni foil " of delivering on the 7th phase < < Intermetallics > > for 1999, and the joint shearing strength obtaining through 1200 ℃ of soldering 42s has reached 320MPa.The people such as the Song Xiaoguo of Harbin Institute of Technology adopt Ti40Ni40Nb20 solder alloy to Ti-45Al-5Nb-(W in the article " Brazing high Nb containing TiAl alloy using TiNi-Nb eutectic braze alloy " of delivering on the 22nd phase < < Intermetallics > > for 2012, B.Y) alloy carries out vacuum brazing, when brazing temperature is within the scope of 1160～1260 ℃, obtained better soldered fitting, shearing strength during gentle 600 ℃ of junction chamber has reached respectively 308MPa and 172MPa.Although adopt the Ti base solder brazing TiAl alloy of above-mentioned research and development can obtain the joint that higher force is learned performance, but brazing temperature is higher, be difficult to meet some and brazing temperature required to the soldering of comparatively harsh TiAl parts, and brazing temperature height easily generates thicker intermetallic compound and can increase the dissolution extent to mother metal.Therefore, be necessary to develop that a kind of low melting point (≤900 ℃), low cost, manufacturing process performance are good, the Ti base solder of joint excellent combination property during soldering TiAl.
