Deformation pathway of HEA sample at 15 K (IMAGE) City University of Hong Kong Caption Deformation pathway of CrMnFeCoNi HEA sample at 15 K. Vertical dashed lines are drawn to pinpoint the changes in the deformation behaviour: (1) Start of dislocation slip; (2) start of stacking faults; (3) first sign of serrations; and (4) massive serrations coincided with the saturation of dislocation slip.
