Description
One, technical field
The present invention relates to metal material field, specifically is a kind of titanium alloy that is used for laser solid forming and laser forming reparation.
Two, background technology
The laser solid forming technology is that a kind of advanced person's of growing up over past ten years 3 D auto increases the material manufacturing technology, is used for the quick manufacturing of compact metal part and the regeneration manufacturing of injuring part (laser forming reparation).At present, laser forming and the selected material of reparation mostly are the powdered material of existing alloy, and alloy species comprises wrought alloy, casting alloy, spray powders alloy or the like.But, the technological process of laser forming and reparation is different from complete processings such as forging, casting, therefore use wrought alloy, casting alloy to wait and carry out laser forming and reparation, formation is different from the microstructure of forging and casting, and then obtain to be different from the mechanical property of forging and foundry goods.Expectation obtains higher mechanical property to the laser forming of metal parts with repairing all, and for example, the performance of expectation laser solid forming spare reaches the forging standard, and the performance behind the expectation laser repairing forging still keeps the forging level.
Titanium alloy since its excellent comprehensive performance in the application in fields such as Aeronautics and Astronautics, navigation more and more widely, the TC4 alloy is a kind of titanium alloy gold the most commonly used.Laser solid forming TC4 alloy directly deposits the mechanical property of attitude and compares the characteristic that presents " high-strength low moulding " with this alloy forged piece, need carry out solid-solution and aging heat treatment and just can make the mechanical property of drip molding and forging suitable.Laser forming reparation for the TC4 alloy forged piece, because part is processed or is used, make that repairing postheat treatment is restricted, repair forging if adopt the TC4 powdered alloy, will there be notable difference in the performance of laser repairing district and forging matrix, the whole use properties, particularly fatigue property of back part repaired in influence.How to make the mechanical property of laser repairing district deposition attitude, only the simple thermal treatment through stress relief annealing just can reach the level suitable with forging, is to realize that the titanium alloy forging high-performance repairs the problem of the necessary solution of institute.The key that addresses this problem be exactly make laser repairing district and forging matrix mechanical property as far as possible approaching.Operational characteristic according to laser solid forming and laser forming recovery technique, adopt the TC4 alloy to form or repair, obtain the performance suitable with forging after being difficult in stress relief annealing, therefore developing a kind of titanium alloy that is used for laser solid forming and laser forming reparation is an important channel that obtains strong mechanical performance.
Three, summary of the invention
Be mechanical property and the unmatched deficiency of TC4 alloy forged piece that overcomes the laser direct deposition TC4 alloy that exists in the prior art, the present invention proposes a kind of titanium alloy that is used for laser solid forming and laser forming reparation.
The present invention comprises titanium, aluminium and vanadium for a kind of titanium alloy that is used for laser solid forming and laser forming reparation, wherein, aluminium 3.6-5.0wt%, vanadium 2.1-3.4wt%, all the other are titanium, and total amount is no more than absolutely.
With respect to the TC4 alloy, the present invention has reduced aluminium, content of vanadium, has reduced the solution strengthening effect in titanium of aluminium, vanadium, the present invention can compare with the laser deposition state property of TC4 alloy, intensity decreases, and plasticity increases, and is suitable with the intensity and the plasticity of TC4 alloy forged piece.The mechanical property of described titanium alloy laser deposition attitude is: tensile strength 910～980MPa, yield strength 840～915MPa, unit elongation 13～17%, relative reduction in area 39～50%.As shown in the table with the contrast of TC4 alloy forged piece standard and measured value:
| Type | σ b/(MPa) | σ 0.2/(MPa) | δ/(％) | Ψ/(％) |
| The laser deposition attitude of described titanium alloy | 910～980 | 840～915 | 13～17 | 39～50 |
| The actual measurement of TC4 alloy forged piece | 930～965 | 870～920 | 14.5～17.5 | 39～43.5 |
| TC4 alloy forged piece standard | ≥895 | ≥825 | ≥8～10 | ≥25 |
The present invention not only can be used for laser forming and reparation, and can be used for high energy beam stream processing technologies such as electron beam deposition shaping, electron beam built-up welding, plasma surfacing, shaping.
