OSTI ID:4032862

An alloy is described whose oxidation resistance is good at temperatures up to and above 11OO deg C and which can be heat treated with conventional means. This alloy contains or may contain Ti, Fe, Cr, V, W, Ta, Ni, Co, Nb, Ba, Si, Be, Y, B, and the rare earth metals. The maximum benefits of the ailoy are obtained when the alloy consists of 5 to 20, l5to 25, 5to 30, 0 to 10, 0 to 20, 0 to 20, 0 to 15, and 0 to 3 wt.% of Ti, Fe, Cr, V, W, Ta, Ni and/or Co, and one or more of Ba, Si, Be, Y, B, and the rare earth metals, respectively, with the remainder being Nb in an amount of at least 40 wt.%; the aggregate of V, W, and Ta must not exceed 30 wt.%. In fabricating the alloy, care should be taken to protect the metals from atmospheric contamination. Pour examples of the alloy are given, and oxidation data are given for temperatures of 8OO, 1000, and 1200 deg C. (D.L.C.)
