Energy landscape depends on the annealing temperature used to prepare the medium-entropy alloy (MEA). a Full dislocation energy pathways for the first Burgers vector. b, c Complex stacking fault energy (CSFE) and antiphase boundary energy (APBE) changes upon increasing number of Burgers vector (on the same slip plane) for a sample with Ta = 950 K. d, e Energy pathways for twinning and face-centered cubic (FCC) → HCP (hexagonal close-packed) martensitic transformation, respectively. Both deformation twinning (DT) and martensitic transformation (MT) are based on the CSF in a. f The average complex stacking fault energy, twin fault energy, martensitic transformation energy, and antiphase boundary energy for random solid solution (RSS) and samples with different Ta (450−1650 K). The unit of the iso-energy circles is mJ/m2
