“…Accordingly, the dominance of compatibility stress in the materials with finer grain size provides the activation stress for <c+a> slip and limits the stable hardening at lower strain. This can be understood in light of the report by yoshinaga et al [42], in that the <c+a> dislocations are split to mobile <a> and immobile <c> components which contribute to severe strain hardening, causing harmful effects on formability at room temperature. This explanation rationalized higher maximum stress as well as lower strain-to-fracture obtained for the material with lower mean grain size.…”

“…These features may apparently be similar to the microtwinning bands in some Mg alloys. 18,19) However, it should be noted in particular that the various rotation angles observed in Fig. 2(b) can never be explained by the primary and secondary twining of the LPSO crystals, suggesting that the micro-kinking is definitely different from the twinning event.…”

“…3.3 Dependence of twinning on grain orientation and the condition of double twinning Similar to the case in single crystals, 2,3,[5][6][7] there is a close orientation dependence of deformation twinning on grain orientation in polycrystalline magnesium. Figure 5 Let us analyze the condition for double twinning.…”

“…Since compression twins are very thin, dislocations for basal slip have relative short distance to operate and may easily cause pile-up at twin boundaries which leads to either tension twinning or cracks as suggested in. 5,6) …”
