Gum metal (Ti-36Nb-2Ta-3Zr-0.3O) is a recently developed multifunctional bcc titanium alloy that exhibits high strength, high ductility and high yield strain. The ideal strength (Tmax) of Gum metal is suggested to be comparable with the actual strength, implying that deformation can occur via ideal shear without any dislocation activity. Calculations indicate that C approaches zero when the average ela value is around 4.24 in Ti-X binary alloys, li is suggested that this is attained in Gum metal, whose e/a is 4.24. The effect of processing route and chemical composition on the deformation mechanisms and mechanical properties of Gum metal were also investigated. ed. A more cost effective processing route involving ingot metallurgy was trialled and the mechanical properties were comparable to the alloys produced via powder metallurgy.
