By contrast, materials such as nickel- and aluminum-based alloys have lower stacking-fault energies, and the rates of recovery are significantly slower. This suggests that microstructural evolution will occur at a slower rate in the latter materials and higher imposed strains will be needed to achieve a reasonable level of ­microstructural homogeneity. 25 GPa: (a) the center of the disk and (b) a region near the edge [28]. 11 Schematic illustration of the variation of the Vickers microhardness across the disk at low total strains in HPT processing for materials having either slow (lower) or fast (upper) rates of recovery [28].

This observation agrees well with the expectation that the shear strain imposed by HPT increases with the radius of the location in the disk and indicates that the plastic deformation in the central area was not significant at this early stage of deformation. 13 [40]. For color details, please see color plate section. Other important features visible at this early stage of HPT deformation are the macroscopic straight shear bands that are usually along radial directions and may pass through the whole disk.
