Fig. 4: Processing routes and formation mechanisms of the PSR.
From: Phase-selective recrystallization makes eutectic high-entropy alloys ultra-ductile
a Schematic illustration of the processing routes and corresponding microstructure evolution. For PSR, the AC EHEA was cold-rolled (CR) 30% and annealed at 1200 °C for two cycles. The FCC phase, B2 phase, PB, and GB/TB are marked in cyan, yellow, black, and red colors, respectively. b In situ μ-DIC results of the AC EHEA during tensile test, revealing the strain partitioning between the FCC and B2 phases during deformation. c Variation of the local von Mises strain along the yellow arrow in b, revealing the much higher strain partitioned to the FCC phase.
