Abstract
PURPOSE: To enhance the high temp. toughness and high temp. ductility of a Co alloy used as a gas turbine material, etc. by adding a restricted amt. of C, Si, Mn, Ni, Cr, W, B, Nb, Zr, Ta, Hf, etc. to Co.
CONSTITUTION: A Co alloy consisting of, by wt., C 0.15W2%, Si≤2%, Mn≤2%, Ni 5W15%, Cr 18W35%, W 3W15%, B 0.003W0.1%, Nb 0.01W1%, Zr 0.05W 0.3%, Ta and/or Hf 1.1W4.5%, and the balance Co and inevitable impurities. In this alloy compsn. the Nb and Zr are combinedly contained with optimum relation to the C, W, B, Cr and Ni contents. By this compsn. superior high temp. strength and high temp. toughness esp. at temps. above 982°C are provided.
