This study analyzes the microstructures of hot-deformed powder materials, considers the physics of processes, what physical changes the powder grains have undergone, which is monocrystallites of different sizes and configurations, the direction of crystallographic planes to the plane of the slot. The influence of the size of the initial particles on the structure formation of powder alloys, taking into account the features of homogenization during sintering, was investigated. The nature of deformation of particles of porous compacts from steel of two types of charge (coarse and fine iron powder, with different porosity) was considered.
