For pure molybdenum nitrided at 1373 K in NH 3 gas, microstructural observations of a molybdenum nitride layer were conducted through a transmission electron microscope. The molybdenum nitride layer consisted of two molybdenum nitrides: an outer one of γ‐Mo 2 N and an inner one of β‐Mo 2 N. A great number of (011)[01] type twins were observed in the β‐Mo 2 N phase, whereas the microstructure of the γ‐Mo 2 N phase was almost free from lattice defects except for slightly observed {111}〈112〉 type twin.
