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 material and a preparation method thereof. The preparation method of the titanium-nickel shape memory alloy target material comprises the following steps that S1, metal titanium and metal nickel are added into a container in an alternate tiling manner to be smelted, and alloy melt is obtained; S2, the alloy melt obtained in the S1 is cast, and cooling is carried out to obtain a target blank; and S3, the target blank is machined, and then the titanium-nickel shape memory alloy target material is obtained. According to the preparation method, the metal titanium and the metal nickel are added into the container in the alternate tiling manner to be smelted, so that the temperature in the smelting process is reduced, air suction in the smelting process is reduced, the purity requirement of the alloy is guaranteed, the smelting speed is increased, and the service life of a smelting furnace is prolonged. In addition, the titanium-nickel alloy target material prepared by the preparation method is uniform in component, low in content of impurities such as C and O, and high in purity.

Description

technical field [0001] The invention belongs to the technical field of shape memory alloy target material preparation, and in particular relates to a titanium nickel shape memory alloy target material 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 titanium, nickel, and copper raw materials are screened, cleaned, and weighed; Induction smelting, including (power transmission, degassing, refining, pouring), to obtain titanium-nickel-copper alloy ingots; then hot isostatic pressing method is used to post-process the poured ingots; finally, the processed ingots are inspected , Cut the riser and the bottom pad to obtain high-purity titanium-nickel-copper ingots. The smelting and casting process of the titanium-nickel alloy ingot prepared by this method is complicated. Although the hot iso...
