The laws of formation of phases and of hardening of binary and complexly alloyed molybdenum alloys with Nb, Zr and Ti under internal nitriding are studied. The structure of thin foils is determined, and the particles of the hardening phases are identified. The distribution of the nitride phases over cross section of 1-mm-thick specimens is studied. The visible length (diameter) and thickness of the particles are measured. The number of particles per unit volume is determined The effective diameters of the nitride particles and the interparticle distance are calculated for the case of their approximation by spheres. The conditions (laws) of high-temperature hardening of molybdenum alloys after internal nitriding are determined.
