Research progress on preparation and forming of titanium andtitanium alloy powders

Titanium and titanium alloys are widely used in military, aviation, and medical fields due to the low density, high strength, corrosion resistance, and good biocompatibility. The traditional production method of casting-forging titanium alloys is complicated and costly, which seriously limits the application of titanium alloys. Powder metallurgy technology can reduce the production cost of titanium alloys, which is expected to popularize the application of titanium alloys. The research status of titanium and titanium alloys by powder metallurgy was introduced in this paper from the aspects of powder preparation and forming process, and the development trend was described.
