DEVELOPMENT OF A STABLE-BETA TITANIUM ALLOY.
Abstract
Alloy bases Ti-17V-10Cr-3Al, Ti-8Mo-8V-7.5Fe 3Al, and Ti-15Mo-5Fe-3Al, containing additions of up to 5% of hardening agents such as Cu, Co and Ni, were water quenched from 1350 F, instead of plate cooled, but no appreciable difference in aging response was found. A marked aging response found when selected alloys were aged at 850 F in the as-cold rolled condition was attributed to alpha precipitation. Reduction of the Fe and Cr contents of the original base alloys and a corresponding increase in the Cu content did not significantly improve fabrication properties. Partial replacement of Fe and Cr by Ni resulted in hot shortness. The possibility of developing titanium alloys hardening by way of rejection of compound from an all-beta matrix is not promising using these additions. (Author)
