Underlying slip/twinning activities of Mg-xGd alloys investigated by modified lattice rotation analysis

The inconsistencies regarding the fundamental correlation between Gd content and slip (twinning) activities of Mg alloys appeal further investigations. However, traditional dislocations analysis by TEM is time-consuming, that SEM/EBSD cannot recognize partial modes. These urge a more efficient comprehensive approach to easily distinguish all potential modes occurred concurrently in alloy matrix. Here we report modified lattice rotation can systems provide statistical results for Using this method, high ductility Mg-Gd ascribed enhanced non-basal slips, cross-slip, postponed twinning addition quantitatively clarified.
