A model of ultrafine microstructure evolution in materials deformed by high-pressure torsion
Original language description
The proposed crystal plasticity model outlines a possible mechanism of a material response under severe plastic deformation as observed in high pressure torsion experiments. A simplified version of the model based on an assumption of uniform deformationof plane-strain double-slip reveals rotations of slip systems caused by the imposed shear strain. An axial compression and a shear stress of twist govern this process. The accompanied continuous reconstruction of the deformation substructure is probablyone of the main reasons of the observed strengthening. Local variations in the crystal lattice orientation are responsible for the microstructure fragmentation. Short-range dislocation interactions control the structural size.
