摘要
回顾了近年来Ti2AlNb合金的研究历程,结合Ti2AlNb合金的应用背景,侧重介绍了粉末冶金近净成形技术制备Ti2AlNb合金的研究现状和应用进展情况,从粉末冶金Ti2AlNb合金的制备、预合金粉末热等静压致密化机制、Ti2AlNb复杂构件研制、粉末冶金Ti2AlNb合金的热变形4个方面对近年来粉末冶金Ti2AlNb合金的主要研究成果进行简要回顾。
A brief summary of historic developments of Ti2AlNb alloy based on orthorhombic phase is presented first. Combined with the specific application background of Ti2AlNb alloy, the research status and application of powder metallurgy(PM) Ti2AlNb alloys in connection with near net shaping technology using hot isostatic pressing(HIP) are mainly reviewed. Key issues such as preparation of PM Ti2AlNb alloys, powder densification during HIP, forming of complex components and hot workability of PM Ti2AlNb alloy were discussed. Future research directions are suggested in the summary section. The bulk of the paper is concerned with progress made in the last 15 years, especially in the last decade.
