Abstract (en)
[origin: EP1647606A1] Precipitation hardened Ni based alloy containing at least 10 vol.% primary metal carbide of composition (wt.%):C (0.5-1.8), Mn (0.5-3.0), Cr (6.0-25.0), Mo (8.0-18.0), W (8.0-10.0), Nb (8.0-3.0), Al (2.5-6.0), Fe 2.5-20.0), Co (2.5-40.0), Ti (2.5-3.0), Hf (2.5-1.5), Ta (2.5-.0), Zr (2.5-0.5) and V (2.5-3.0). Independent claims are included for: (1) a method of preparing an object from the Ni based alloy containing the above elements in the amounts listed from a powder compact with calcining over the temperature range between the solution temperature of the gamma'-phase and the solidus temperature; (2) a tool, especially a welding tool or thermally loaded transformation tool comprising the Ni based alloy as described above; (3) a starting material for preparation of a welding tool or thermally loaded transformation tool comprising the Ni based alloy as described above.
