Crystallogeometric peculiarities of subrain structure nad and their connection with deformation texture

Distributions of orientations and relative disorientations subgrains in polycrystal molybdenum have been studied experimentally. The results are discussed from the viewpoint of the mechanism of subgrain structure formation and origin of deformation textures. It is established that in the process of deformation the parts of grain adjoining its boundaries undergo the greatest reorientation. It means that during high-temperature deformation grain boundaries are a very important source of plastic rotations
