“…Generally, the phase transformations were enhanced by increasing ε eq . 2,38) However, previous studies on pure Co 15,39) and steel 5) processed by HPT have reported the decrease in the volume fraction of ε phase through HPT processing, which could be attributed to a possible reverse transformation. 25) It has been reported that a reverse ε→γ transformation occurred in Co, when the grain diameter was below 100 nm.…”

“…16B). In this study, rather than the directional DTs cutting other DTs/DT intersections (Lu et al, 2010), the SBs cutting through the DTs/DT intersections are more frequently observed, indicating that the shear bands cutting the grains and DTs can be the dominant refinement mechanism at a high deformation (Fig. 12B, Fig.…”

“…An interesting deformation microstructure was the formation of a third-directional DT which cut the two-directional DT-DT intersections. This is considered to be the main grain refinement mechanism as proposed by Lu et al (2010). Even though various deformation microstructures have been reported in the surface of the deformed stainless steels, more comprehensive studies of the shot peening induced depth-dependent structures still needs to be done.…”
