摘要: Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, with significant weight-savings while maintaining comparable mechanical properties. New gamma titanium aluminide alloys and an appropriate fiber could offer improved TMC use intermediate applications (400-800 C). The purpose of this investigation is the evaluation a alloy nominal composition Ti-46.5Al-4(Cr,Nb,Ta,B)at.% as material future aerospace transportation systems, where very light-weight structures are necessary meet goals advanced programs.
