摘要： A high strength and high toughness Mo alloy worked material, characterized in that it is produced through subjecting a Mo alloy worked material comprising an Mo base phase and, incorporated in the form of a solid solution with the Mo phase, a metal element capable of forming a nitride and, precipitated and dispersed in the Mo phase, at least one of carbide particles, oxide particles and boride particles to an internal nitriding, and fine nitride particles are also dispersed in addition to the at least one of carbide particles, oxide particles and boride particles; and a method for producing the above novel material which comprises subjecting an alloy worked material comprising an Mo base phase and, precipitated and dispersed therein, at least one of carbide particles, oxide particles and boride particles and, incorporated in the form of a solid solution with the Mo phase, at least on of Ti, Zr, Hf, V, Nb and Ta to a multi-step internal nitriding wherein the treatment temperature is stepwise elevated. The high strength and high toughness Mo alloy worked material can be used at a temperature higher than the temperature at which conventional TZ alloy is used.

摘要： 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.
