<p>The alloy has the compn. 0.005-0.05% B, 0.02-0.2%C 5.0-7.0% Al, 3.0-10.0% Cr, 5.0-15.0% Co, 0-0.5% Zr 0.2-3.0% Ti, 0-3.0% Nb, 0-6.0% Hf, 0-8.0% Ta, 0-56.0% Mo, 0-8.0% V, balance Ni, and usual impurities. The alloying elements are divided into 3 gps. (a) B, C, Al, Cr, Co, Zr, and Ni (b) Ti, Nb and Ta, (c) Mo and W, and adds. of those from group (b) and (c) may be varied so that the total addns. from these 2 gps is at a constant atomic concn. of 3%.</p> |
