Abstract:
A composition comprisinga first alloy consisting essentially of a base element of about 45 to 91.5 wt % titanium and at least one secondary element selected from the group consisting of 0.01-43.5 wt % chromium, 0.01-26.3 wt % aluminum, 0.01-74.5 wt % niobium, 0.01-2.25 wt % boron, 0.01-71.5 wt % silicon, 0.01-53.5 wt % germanium, and mixtures thereof, said first alloy having first melt temperature between about 1300Â° C. and about 1590Â° C.; and a second alloy consisting essentially of: a base element selected from the group consisting of 0.01-91.5 wt % titanium, 0.01-74.5 wt % tantalum, 0.01-98.3 wt % niobium, 0.01-89.5 wt % hafnium, 0.01-71.5 wt % silicon, and 0.01-53.5 wt % germanium, and at least one secondary element different from said base element and selected from the group consisting of 0.01-43.5 wt % chromium, 0.01-26.3 wt % aluminum, 0.01-74.5 wt % niobium, 0.01-2.25 wt % boron, 0.01-71.5 wt % silicon, 0.01-53.5 wt % germanium, and mixtures thereof and having a second melt temperature between about 1500Â° C. and about 1675Â°.
