Problems solved by technology

The smelting and casting process of the titanium-nickel alloy ingot prepared by this method is complicated. Although the hot isostatic pressing method can eliminate the technical problems of metallurgical defects formed by smelting, the processing cost is also high. To a certain extent, it can achieve stable oxygen content and crystal The purpose of fine grain structure and reduction of metallurgical defects, but the operation is complicated and the effect is not good

Abstract

The invention discloses a titanium-nickel shape memory alloy target and a preparation method thereof. The preparation method of the titanium-nickel shape memory alloy target material includes the following steps: S1: adding metal titanium and metal nickel into a container in an alternately tiling manner, and smelting to obtain an alloy melt; S2: adding the alloy melt obtained by S1 to Casting and cooling to obtain a target blank; S3: machining the target blank to obtain the titanium-nickel shape memory alloy target. In the present invention, metal titanium and metal nickel are added into the container in an alternately tiling manner for smelting, which is beneficial to lowering the temperature in the smelting process and reducing the inhalation during the smelting process, which not only ensures the purity requirements of the alloy, but also improves the smelting speed and smelting speed. furnace life. In addition, the titanium-nickel alloy target prepared by the preparation method has uniform composition, low content of impurities such as C and O, and high purity of the target.

Description

technical field [0001] The invention belongs to the technical field of shape memory alloy target preparation, in particular to a titanium-nickel shape memory alloy target and a preparation method thereof. Background technique [0002] Chinese invention patent (CN109666813) discloses a method for preparing a high-purity titanium-nickel-copper memory alloy ingot. The specific steps are as follows: firstly, the raw materials of titanium, nickel and copper are screened, cleaned and weighed; then vacuum is carried out according to preset conditions. Induction smelting, including (power transmission, degassing, refining, pouring), to obtain titanium-nickel-copper alloy ingots; then post-treatment of the poured ingots by hot isostatic pressing; finally, flaw detection of the treated ingots , Cut the riser and the bottom pad to obtain a high-purity titanium-nickel-copper ingot. The titanium-nickel alloy ingot prepared by this method has complicated smelting and casting process oper...
