主　　题：Mg-Gd alloy Non-basal slips Postponed twinning Grain boundary segregation Modified lattice rotation analysis 

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