摘要：A Co-base alloy which has a basic composition including, in terms of massproportion, 0.1% - 10% Al, 3.0 - 45% W, and Co as the remainder and has an intermetalliccompound of the Ll2 type [Co3(Al,W)] dispersed and precipitated therein. Part of the Comay be replaced with Ni, Ir, Fe, Cr, Re, or Ru, while part of the Al and W may be replacedwith Ni, Ti, Nb, Zr, V, Ta or Hf. The intermetallic compound [Co3(Al, W)] has a high meltingpoint, and this compound and the matrix are mismatched little with respect to latticeconstant. Thus, the cobalt-base alloy can have high-temperature strength equal to thatof nickel-base alloys and excellent structure stability.
