Структура субмикрокристаллических сплавов Сu - Al

Abstract

According to experimental data and the proposed models for all modes of severe plastic deformation, fragmentation of the grain structure in metals and alloys is ensured by the development of shear plastic deformation without the formation of pores and microcracks. Structure of copper and alloys Cu - 5 at. % Al after cold rolling and abc-pressing was researched by methods of backscattered electrons and X-ray diffraction. And it founded that after rolling the grain-subgrain structure remains submicrocrystalline with follower dynamic recrystallization.
