Abstract
The present invention relates to one kind of low temperature super elastic four-component Ti-Ni alloy and its preparation and application. The present invention features that the alloy consists of Ni 55.3-56 wt%, V 0.40-0.90 wt%, Al 0.05-0.15 wt%, except Ti and inevitable impurities, including C not more than 0.070 wt%, H not more than 0.005 wt% and O not more than 0.050 wt%. The alloy is especially suitable for use in making spectacle frame, cellphone antenna and other devices needing low temperature elasticity.
Description
Technical field
The present invention relates to be applied to a kind of super-elasticity titanium nickel (TiNi) alloy product and preparation method thereof under the cold condition.
Background technology
Titanium nickel TiNi alloy not only has peculiar shape memory effect, but also has superior superelastic properties, and mainly is used widely in spectacle frame, antenna for mobile phone field.The TiNi alloy can show excellent non-linear superelastic properties after certain technology special processing, the maximum elastic strain amount can reach 8%, presents than the much bigger elasticity of other metallic substance (general recoverable strain amount is no more than 1%).The binary Ti-Ni alloy of real world applications presents the temperature of 5% non-linear superelastic properties more than 5 ℃, 5 ℃ of obvious variation of the non-linear superelastic properties of following temperature alloy.
When titanium nickel (TiNi) alloy is applied to spectacle frame, antenna for mobile phone, require to present non-linear preferably superelastic properties under low-temperature condition, i.e.-10 ℃～40 ℃ temperature ranges, after 6% recoverable deformation, recovery rate is greater than 95% after the requirement silk material cold working timeliness; After the cold working straight line was handled ,-25 ℃～40 ℃ temperature ranges, after 5% recoverable deformation, recovery rate was greater than 90%.Reality needs the use temperature interval to present the new Ti-Ni alloy goods and the preparation method of good non-linear superelastic properties in above scope.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of low temperature super elastic titanium nickel (TiNi) quad alloy is provided.
Can take following technical scheme to realize purpose.
The Ni-based quad alloy goods of titanium, by weight percentage, it consists of: nickel: 55.3%～56.3%; Vanadium: 0.40%～0.90%; Aluminium: 0.05%～0.18%, surplus is titanium and unavoidable impurities, wherein low gap constituent content carbon C≤0.070%; Hydrogen H≤0.005%; Oxygen O≤0.050%.
Low temperature super elastic of the present invention adopts a certain proportion of aluminium vanadium (AlV) alloy as additive with new titanium nickel (TiNi) alloy, reduces the martensitic transformation temperature of alloy, improves the homogeneity of ingot casting composition simultaneously.
Alloy preparation process of the present invention is that the element that will reduce martensitic transformation temperature adds with aluminium vanadium (AlV) alloy form, and element titanium (Ti) adds with the titanium sponge form, and elemental nickel (Ni) adds with the electrolytic nickel strips.The melting in vacuum induction furnace of batching back, by forge, rolling, swage, stretch, align preparation all size rod silk material.
