Essay

The high-temperature 'in-situ' diffractometry method was used to study phase transformations in specimens of several types of new materials. It has been established presence and regular arrangement of metal vacancies in Mo2C and Nb2C carbides. For the Al-Ti-Cr system, it has been established the existence alloys, in which at 1273 K the two solid phases with cubic structures is presence. The phase equilibriums at presence a nano- and quasicrystal phase were studied. An influence of a structural state of the alloys on their hydrogen-sorption properties was investigated.
