چکیده انگلیسی
{101Ì
1} twinning played an important role during hot-rolling process of AZ31 alloy. In the present work, TEM was employed to investigate such twinning related plastic mechanism. The dislocations were usually lying on the basal plane in matrix, while aâ+câ slip was usually activated near grain boundary as well as in twinned area even when the orientation was quite soft for basal slip. The combination of aâ and aâ+câ slip created the characteristic misorientation relationship along ã112Ì
0ã in twin region. The activation of non-basal slip met the requirement to accommodate adequate localized stain in twinned area, which made twinning induced DRX kinetically possible. The twin lamella with the highest SF, which was supposed to be the most effective in accommodating imposed strain, showed the highest tendency for localized strain and led to complete DRX inside twinned region.
