[ 1 ] - Limit of Dislocation Density and Ultra-Grain-Refining on Severe Deformation in Iron

It is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (DCR). However, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. In general, multi-directional defor...
