Abstract (en)

[origin: EP1491651A1] Nitrided molybdenum alloy worked material (1) comprises base molybdenum alloy worked material and molybdenum nitride layer (4) formed on the surface. The base worked material contains fine nitride particles (2) formed by nitriding a metal element present inside the worked material. The nitride layer is formed by nitriding a worked structure or a recovered structure.
