|Title||COBALT-BASE ALLOY WITH HIGH HEAT RESISTANCE AND HIGH STRENGTH AND PROCESS FOR PRODUCING THE SAME|
A Co-base alloy which has a basic composition including, in terms of mass proportion, 0.1% - 10% Al, 3.0 - 45% W, and Co as the remainder and has an intermetallic compound of the Ll 2 type [Co 3 (Al,W)] dispersed and precipitated therein. Part of the Co may be replaced with Ni, Ir, Fe, Cr, Re, or Ru, while part of the Al and W may be replaced with Ni, Ti, Nb, Zr, V, Ta or Hf. The intermetallic compound [Co 3 (Al, W)] has a high melting point, and this compound and the matrix are mismatched little with respect to lattice constant. Thus, the cobalt-base alloy can have high-temperature strength equal to that of nickel-base alloys and excellent structure stability.
