Abstract
Niobium aluminides for structural applications to operate beyond the o perating temperatures of conventional nickel-base superalloys have bee n assessed over the past few years. The niobium aluminides have extrem ely high strength at elevated temperatures, above 1000 degrees C. Brit tleness at ambient temperatures is alleviated by incorporating a ducti le phase, and poor oxidation resistance is being improved by macro- or micro-alloying.
