ALLOY FOIL CAPABLE OF LIQUID-PHASE DIFFUSION WELDING OF HEAT-RESISTING MATERIAL IN OXIDIZING ATMOSPHERE

摘要

An alloy foil capable of effecting the liquid-phase diffusion welding in an oxidizing atmosphere of a heat-resisting material which is difficult to weld. The foil comprises 6.0-15.0 mass % of Si, 0.1-2.0 mass % of Mn, 0.50-30.0 mass % of Cr, 0.10-5.0 mass % of Mo, 0.50-10.0 mass % of V, 0.02-1.0 mass % of Nb, 0.10-5.0 mass % of W, 0.01-0.5 mass % of N and 0.50-20.0 mass % of P, further containing 0.005-1.0 mass % of C and one or two of 0.01-5.0 mass % of Ti and 0.01-5.0 mass % of Zr, and the balance consisting of Ni and impurities, and has a thickness of 3.0-300 mu m; or a substantially vitreous alloy foil of the above-mentioned composition capable of effecting the liquid-phase diffusion welding of a heat-resisting material in an oxidizing atmosphere.
