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。
Due to the fact that fine and homogeneous Ti-Al intermetallic compounds can be prepared, powder metallurgy technology has a great advantage in the application of Ti-Al intermetallic compounds. Taking Ti-23Al-17Nb (at%) and Ti-45Al-2Cr-2Nb- (B, W) (at%) as examples, the effects of powder metallurgy on the preparation and forming of Ti-Al intermetallic compounds Of the preparation process, performance and some samples, shows the Ti-Al-based intermetallic compounds in space and weapons models of good prospects.
