Abstract
Structure formation of powder austenite produced with different compaction schematic diagrams is considered. It is found the steady fragmented austenite structure to be formed during compression in a closed die and transversal compaction. High degree and rate of deformation are shown to be ensured during hot forming according to the extrusion and non-equiaxial all-around compression resulting in preferential development of dy- namic and static recrystallization. In increasing the deformation degree according to the free compaction schematic diagram, the recrystallized grain sizes are reduced.
