• a) providing a metal alloy;
• said metal alloy including at least about 55 wt. % of a solid solution of rhenium and molybdenum alloy;
• said metal alloy including at least about 20 wt. % rhenium and at least about 20 wt. % molybdenum;
• said metal alloy including about 0.01-35 wt. % of an additional metal additive;
• said additional metal additive includes i) one or more metals selected from the group consisting of hafnium and technetium, or ii) two or more different metals selected from the group consisting of hafnium, osmium, technetium, vanadium, and titanium;
