  • ABSTRACT: The conditions of interaction of a solid-reinforcing inclusion with a metal matrix of a dispersed- reinforced composite material in the focus of deformations during isothermal pressing are considered. As a result of numerical modeling, the mechanism of reorientation in the direction of metal flow of solid reinforcing inclusions is substantiated. It is shown that the mechanism of rotation of the inclusion in the direction of flow of the metal depends on the gradient of the velocities of the material particles of the matrix. It is shown that the use of back pressure improves the interaction conditions at the boundary surface of the inclusion and the matrix, reduces the likelihood of microcracks, and the process in hot plastic deformation creates conditions for "healing" of existing microdamages.
