Abstract
These multiscale measurements were used to discuss: the transformation sequence, nuances of the stress-strain curve such as strain hardening and softening, the hysteretic behavior, the strain-rate dependence, twinning strain, twin-twin intersections, twin fraction evolution, dynamic strain aging, grain interactions, mesoscopic slip bands, and a RVE size.
