Ti-Fe-Sn-Nb alloys comprised of single β-Ti phase were developed showing excellent mechanical strength and superior plasticity. The alloys exhibited increased yield strength as a function of Fe content, where the Ti80Fe14Sn3Nb3 alloy presented the highest yield stress (1.88GPa) comparable to that of...
