Niobium-silicide based compositions, and related articles

摘要

A refractory composition comprising niobium and silicon is disclosed. The amount of silicon present is less than about 9 atom %, based on total atomic percent for the composition. A turbine engine component (e.g., a gas turbine) is also described herein. The component comprises an alloy of niobium and silicon, wherein the amount of silicon present is less than about 9 atom %.
