First-principles investigation on the brittleness mechanism of TiAl alloys and the effect of doping

TiAl alloys are widely used in aerospace applications due to their excellent performance and lightweight characteristics. However, their intrinsic brittleness has somewhat limited their further development. In this study, first-principles calculations are performed on TiAl alloys and their compounds...
