Abstract One of the characteristic features of Mn-Cu binary alloys nitrided by gaseous nitrogen is that one of the two constitutive elements (Mn) can form nitrides, while the other one (Cu) does not give any stable compound with nitrogen. The only mixed manganese-copper nitride is the CuMn 3 N compound. The reaction kinetics with nitrogen are very slow and there is no internal nitriding. For alloys containing less than 20 at.% Mn, nitrogen reacts very little. The nitride scale formed on the alloys of greater Mn concentrations is a mixed nitride whose formula is Cu 1−x Mn 3+x N. The techniques of examination used are SEM, EMA, and GDS analysis.
