Abstract
Ti-Al alloys with various alloying additions show promise as high temp erature materials because of their high temperature strength and modul us. Recent strides in processing and microstructural control produced alloys which exhibit an acceptable balance of properties for aerospace applications. However, little is known about the influence of the hig h temperature exposures, which these materials will experience in serv ice, on the mechanical properties. Therefore, a study was undertaken t o examine the effects of thermal exposure on the tensile properties of two wrought alloys: Ti-47Al-2Mn-2Nb and Ti-47Al-1.6Cr-0.9V-2.4Nb. The effects of microstructure and exposure at temperatures spanning the a nticipated use range were investigated.
