Abstract (en)
Disclosed herein is a nickel-based heat-resistant alloy for dies containing: 0.01-0.5 wt% Zr, 0.04-0.2 wt% Mn, 0.04-2.5 wt% Si, at least one selected from the group consisting of 3.0-8.5 wt% Al, 1.7-4.8 wt% Ti and 0.87-2.5 wt% Nb, and one or both of 13-25.0 wt% Mo and 6.7-13 wt% W, and having 30-88% by volume of the gamma phase, 12-60% by volume of the gamma ' phase and 2.5-11% by volume of the alpha phase, the balance being essentially Ni. The alloy may further contain at least one selected from the group consisting of 0.03-2 wt% Hf, 0.3-3 wt% Ta and 3-10 wt% Cr. The alloy has excellent strength, ductility and oxidation resistance, and is excellent in high-temperature strength at 1000 DEG C or above. Therefore, the nickel-based heat-resistant alloy for dies exhibits high performance as a material for dies to be used for forging at high temperatures. <IMAGE>
