Description
| - The grain refinement observed in metals exposed to severe plastic deformation (SPD) is interpreted as an energy minimization process. For a crystalline solid it is less energetically costly to be fragmented in small regions (subgrains) deformed by a reduced number of slip systems and fitted together by local reorientations than to be deformed by homogeneous multislip. The energy minimization enhanced by hardening tends to reduce the size of the subgrains. On the other hand, the refinement increases the area of the boundaries between the subgrains, hence, it increases interface energy. The effective rotation of the active slip systems, which is a basic characteristic of SPD processing techniques, enhances the refinement process. It is proposed that the effective rotation causes a continuous reconstruction of the substructure pattern. The hindered destruction of the previous pattern leads to an increased hardening thus reducing the size of the subgrains.
