Fig. 4 Grain orientation and phase distribution of 304 SS treated using 8 mm Ø 316L stainless
steel balls for 60 min, assessed at the cross-section covering a region of 130 μm from the top of the
treated surface to the bulk, by EBSD analysis (top edges correspond to the top surface of the treated
304 SS): a inverse pole figure (IPF) map showing the orientation of fragmented and deformed
grains; b phase-contrast map taken at the same region shown in panel a, indicating the formation
of the strain-induced martensite phase after SMAT; red and green colors represent martensite and
austenite phases respectively; and the fraction of these phases are also included in panel b (Reprinted
