钛及钛合金粉末制备与成形工艺研究进展

Research progress on preparation and forming of titanium andtitanium alloy powders

摘要: 钛及钛合金因具有密度低、强度高、耐腐蚀、生物相容性好等特点被广泛应用于军事、航空、医疗等领域。传统铸锻钛合金生产工艺复杂，成本高，严重限制了钛合金的应用，粉末冶金技术制备钛合金降低了生产成本，有利于钛合金的推广应用。本文从钛及钛合金粉末的制备与成形工艺方面介绍了粉末冶金钛及钛合金的研究现状，并阐述了其发展趋势。

Abstract: 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.
