Figure 4. Gradient structures created by LST techniques: (A and B) Cross-sectional EBSD images of CrFeCoNiMn0.75Cu0.25 MPEA processed by 1 and 4 cycles of LSP, respectively[86]. (C and D) Grain size distribution of as-fully recrystallized (CrCoNi)92Si4B4 MPEA after and before LSR[87]. (E1 and E2) grain distribution of inverse gradient LSR-CoCrFeMnNi, more details are given in (F) and (G) for clear view of local microstructures containing heat-affected zone (HAZ) and fusion zone (FZ)[89].
