摘要

粉末冶金工艺可有效避免铸锭冶金带来的成分偏析、组织粗大、缩松缩孔等问题，是TiAl金属间化合物制备的重要研究方向。从粉末制备、烧结、成形、热处理4个方面对TiAl金属间化合物粉末冶金工艺的研究进展进行了介绍，重点评述了冷壁坩埚真空气雾化、电极感应熔炼气雾化、热等静压等制备技术，对粉末冶金制备TiAl金属间化合物的研究方向进行了展望。

Abstract

Powder metallurgy (PM) TiAl-based alloy can solve the problems associated with ingot metallurgy

such as composition segregation

coarse microstructure and shrinkage cavity. In this paper

recent progress of PM TiAl-based in termetallics in powders preparation

sintering

forming and heat treatment was reviewed. Some methods were introduced including cold crucible vacuum induction melting gas atomization (VIGA–CC)

electrode induction melting gas atomization (EIGA)

hot isostatic pressing (HIP). Furthermore

the research direction of PM TiAl-based intermetallics was pointed out.
