The major hurdle to be overcome for commercial use of the gamma-based titanium aluminides is their poor ductility under ambient temperatures. Substantial research efforts have been devoted to improve the ductility by adding alloying elements and most commercially important alloys contain certain amount of beta-stabilising elements such as V, Mn, Mo, Nb, Ta, Cr etc, resulting in continuous improvement. It was not until recently however, that non-conventional beta-stabilising elements from plat...
