摘要：
The invention relates to a Ni-base alloy which contains Mo, Al and Fe, and further, as required, one or more of the following: a group consisting of one or more of V, W, Cr and Cu; one or both of B and Ca; and Co. The alloy of the invention has excellent resistance to stress corrosion cracking even after being subjected to thermal processing such as welding without need for solution treatment thereafter.
