图10 计算M因子时晶界两侧滑移系的2种情况示意图 |
Fig.10 Schematics of two situations of the slip systems on both sides of the grain boundary when calculating M factor (Incoming slip plane—the slip plane in current grain, out-going slip plane—the slip plane in the grain in front of the grain boundary, nin—the normal direction of incoming slip plane, nout—the normal direction of out-going slip plane, (a) the slip planes on both sides of the grain boundary are identified (b) the slip plane in front of the grain boundary is uncertain, all 4 octahedral slip planes should be considered |
