Abstract
The invention relates to a super elastic alloy material which comprises the following components according to the atom percentage composition: 45-55at% of nickel, 0-10at% of iron, 25-35at% of titanium and 5-15at% of cobalt. The super elastic alloy material provided by the technical scheme has a narrow lag super elastic property and can keep a shape memory effect.
Description
Technical field
The invention belongs to functional technical field of alloy material, refer to especially a kind of superelastic alloy material.
Background technology
Superelastic alloy is widely used in the fields such as aviation, machinery, precision instrument and medical treatment because it has higher recovered elastic deformation.The superelastic alloy that the most often uses at present is Ti-Ni alloy, there is thermo-elastic martensite in the Ti-Ni alloy, its transformation temperature changes within the specific limits with the alloy ingredient difference, because the nickel titante series alloy not only has peculiar shape memory effect, also has preferably super-elasticity behavior, but its super-elasticity behavior belongs to the super-elasticity behavior of wide transformation hysteresis, so in-fighting is high.
Adopt cobalt Substitute For Partial nickel among China patent publication No. CN102337424 and form a kind of nickel ferro-cobalt gallium alloy material, think to obtain preferably super-elasticity behavior by the martensitic transformation temperature that can change and control alloy material.Analyze by the alloy to this technical scheme, the elastic performance of this alloy is better than common Ti-Ni alloy really, martensite also corresponding minimizing is a lot, but this alloy also has certain defective, has super-elasticity although Here it is, but the shape memory effect for former Ti-Ni alloy greatly reduces, even shape memory effect is zero in some component.Therefore need to develop a kind of alloy material that narrow hysteresis elastic performance can keep again shape memory effect that namely has.
Summary of the invention
The objective of the invention is by a kind of technical scheme is provided, the alloy material of this technical scheme not only has the alloy material that narrow hysteresis elastic performance can keep again shape memory effect.
The present invention is achieved by the following technical solutions:
A kind of superelastic alloy material, it is nickel 45-55at% that each of described alloy material forms by atomic percentage conc, iron 0-10at%, titanium 25-35at%, cobalt 5-15at%.
As further improvement, it is nickel 50at% that each of described alloy material forms by atomic percentage conc, iron 5at%, titanium 35at%, cobalt 10at%.
The invention has the beneficial effects as follows:
1, the alloy material of the technical program not only has the alloy material that narrow hysteresis elastic performance can keep again shape memory effect.
2, the production technique of the technical program is simple, is easy to suitability for industrialized production.
Embodiment
Below by embodiment technical scheme of the present invention is elaborated.
A kind of superelastic alloy material, it is nickel 45-55at% that each of described alloy material forms by atomic percentage conc, iron 0-10at%, titanium 25-35at%, cobalt 5-15at%.
As further improvement, it is nickel 50at% that each of described alloy material forms by atomic percentage conc, iron 5at%, titanium 35at%, cobalt 10at%.
Described a kind of superelastic alloy material preparation method specifically may further comprise the steps:
1), choose the nickel of purity 〉=99.9%, purity 〉=99.99% cobalt, the iron of purity 〉=99.9%, the titanium of purity 〉=99.9% is prepared burden above-mentioned materials according to atomic percentage conc, then put into the non-consumable vacuum arc melting furnace and be evacuated to 2.0 * 10
-4Pa is filled with argon gas again, inhales casting with mold cools down after the melt back and obtains alloy blank;
2), with 1) in the alloy blank sealing that obtains, be evacuated to 5.0 * 10
-5Pa 1000 ℃ of lower insulations 72 hours, then is cooled to room temperature and obtains the superelastic alloy material.
Described cooling to be at the uniform velocity being cooled to the master, rate of cooling remain on 2.5-5 ℃ per 15 minutes, this rate of cooling will remain to the blank drop in temperature to 450-500 ℃.The result who does like this is can keep the interior crystalline structure of alloy even, and each particle that forms in unit volume is roughly the same, reduces the in-fighting of energy.
