Abstract
A niobium-silicide based alloy and a turbine having at least a turbine component formed from the niobium-silicide based alloy are provided. The niobium-silicide based alloy comprises: between about 14 atomic percent and about 24 atomic percent titanium (Ti); between about 11 atomic percent and about 19 atomic percent silicon (Si); between about 4 atomic percent and about 8 atomic percent chromium (Cr); between about 2 atomic percent and about 6 atomic percent hafnium (Hf); up to about 4 atomic percent aluminum (Al); between about 0.5 atomic percent and about 1 atomic percent tin (Sn); between about 5 atomic percent and about 15 atomic percent tantalum (Ta); between about 1 atomic percent and about 5 atomic percent tungsten (W); up to about 5 atomic percent rhenium (Re); up to about 5 atomic percent zirconium (Zr); up to about 6 atomic percent yttrium (Y); and a balance of niobium (Nb).
