| Abstract |
The process of secondary recrystallization in the Mg-6Sn binary alloy that initially had bimodal grain size distribution was observed. The prevalence of the {0001}//sheet plane orientation in the initial texture was destroyed and the texture was transformed to a very strong {2□□0}-type during solution heat treatment at 480 ℃. The grain boundary character was analyzed using EBSD, in which no preference of the CSL boundary among the grain boundaries of {2□□0}- oriented grains was evident. It was observed that some fine grains were isolated within coarse {2□□0} oriented grains due to limited boundary migration and these boundaries belonged to CSL boundaries. These analyses confirmed that the secondary recrystallization was driven by the general high-angle grain boundaries surrounding {2□□0}-oriented grains. (Received July 31, 2013) |
