UNS N10629: A new Ni-28%Mo alloy

Early published work about alloys in the nickel-molybdenum system (namely, alloys B [UNS N10001] and B-2 [UNS N10665]) is reviewed. Results of several recent studies to prevent thermomechanical cracking during fabrication of components and stress corrosion cracking during service for alloy B-2 are presented. Data for a new alloy, UNS N10629, which has better alloy composition control than alloy B-2, also are given.
