Injection molding titanium alloy deoxidizing process and application

Abstract

The invention relates to an injection molding titanium alloy deoxidizing process. The invention particularly relates to a method for producing a high-performance low-oxygen injection molding titaniumalloy part and application. By taking titanium powder and / or titanium alloy powder with high oxygen content and low cost as raw materials for the first time, a product with excellent performance is obtained through a conventional injection molding process matched with a special reduction method in the later period. The raw materials are low in price, and the preparation process is simple and controllable; the obtained product is stable in size and excellent in performance. The process designed by the invention is particularly suitable for preparing thin-walled parts.

Description

technical field

[0001] The invention relates to an injection-molded titanium alloy oxygen removal process; in particular, it relates to a method and application for producing high-performance low-oxygen injection-molded titanium alloy parts. Background technique

[0002] Titanium alloys have a series of advantages such as low density, high specific strength, corrosion resistance, weldability, good medium temperature performance, and non-magnetic properties. They are widely used in aerospace, nuclear energy and chemical industries. Injection molding is a near-net shape technology using metal powder as raw material, which usually includes powder preparation, feed preparation, injection, degreasing, sintering, post-processing and other processes. This technology can achieve near-net shape of titanium products without processing, Compared with the traditional processing technology, it has the advantages of high flexibility in product shape, high mass production efficiency, low c...
