Abstract
A metastable beta titanium-base alloy of Ti-Fe-Mo-Al, with a MoEq. greater than 16, preferably greater than 16.5 and preferably 16.5 to 20.5 and more preferably about 16.5. The alloy desirably exhibits a minimum percent reduction in area (% RA) of 40%. Preferred composition limits for the alloy, in weight percent, are 4 to 5 Fe, 4 to 7 Mo, 1 to 2 Al, up to 0.25 oxygen and balance Ti.
Claims18
A metastable beta titanium-base alloy consisting essentially of Ti-Fe-Mo-Al with Fe and Mo each being at least 4 weight percent, and with said alloy having a MoEq. greater than 16.
A metastable beta titanium-base alloy consisting essentially of, in weight percent, 4 to 5 Fe, 4 to 7 Mo, 1 to 2 Al, up to 0.25 O.sub.2 and balance Ti and incidental impurities.
A metastable beta titanium-base alloy consisting essentially of, in weight percent, 4 to 5 Fe, 4 to 7 Mo, 1 to 2 Al, up to 0.25 O.sub.2 and balance Ti and exhibiting a minimum % RA of 40% in the solution-treated condition.
