Fatigue and Fracture of Titanium Aluminides
TL;DR: In this paper, the authors evaluated monolithic titanium aluminides for static components where they offer strength and stiffness advantages at temperatures above conventional titanium alloy capability, and showed that using them in major structural and rotating components could significantly increase the engine thrust-to-weight ratio.
