Joining of Powder Metallurgy Beta Gamma Titanium Aluminide Through Diffusion Brazing

Abstract

This thesis presents an experimental study of diffusion brazing powder metallurgy beta gamma titanium aluminide, along with a methodology utilizing pentenary equivalent beta forming effectiveness for the design of post bond heat treatments. Beta gamma titanium aluminides are attractive high temperature materials with low density and high specific strength. Adequate joining and repair methods, and the re-
