摘要
PURPOSE: To obtain a structural material having lower density, higher strength at higher temps., good ductility at a room temp. and higher oxidation resistance. ;CONSTITUTION: A composite structural material having a high density and high strength reinforcing niobium base alloy embedded within a lower density and lower strength niobium base alloy is provided. As the matrix, an alloy of a niobium and titanium base expressed by the following formula is preferably used: Nb-Ti27-40.5-Al4.5-10.5-Hf1.5-5.5 Cr4.5-8.5 V0-6, where each metal of this metal/ metal composite has a body centered cubic crystal structure, and wherein the ratio of concentrations of Ti to Nb(Ti/Nb) is ≥0.5, and the maximum concn. of the Hf+V+Al+Cr additives is ≤16.5+(5×Ti/Nb).;COPYRIGHT: (C)1994,JPO
