    摘要:

    由于可以制备出组织细小、均匀的Ti-Al 系金属间化合物材料,粉末冶金技术在Ti-Al 系金属间
    化合物材料的应用研究方面具有很强的优势。本文以Ti-23Al-17Nb( at%) 和Ti-45Al-2Cr-2Nb-( B, W)
    (at%)为例,介绍了粉末冶金技术在Ti-Al 系金属间化合物材料制备及成形方面的制备工艺、性能和部分样
    件,展示了Ti-Al 系金属间化合物材料在航天及武器型号方面良好的应用前景。

    Abstract:

    Because of capability of preparation for Ti-Al based intermetallics with fine and uniformity micro鄄
    structures, powder metallurgy processing method has an unique application in preparing Ti-Al based intermetallics.
    Using the examples of Ti-23Al-17Nb (at%) and Ti-45Al-2Cr-2Nb-(B, W)(at%) alloy, the paper introduces
    the fabrication, shaping and properties of Ti-Al based intermetallic prepared by powder metallurgy processing, and
    shows a good prospect of applications in the aerospace areas.
