Effects of a grain boundary (GB) on local mechanical properties in magnesium were investigated by nanoindentation. Based on the evaluated activation volume values, it was found that pop-in phenomena in matrix and near GB could be attributed to equivalent defect events. The pop-in load and hardness were higher for indentation near GB than in matrix, due to dislocation-GB interaction. Formation of {1012} deformation twins was observed in the vicinity of the indents. The twin growth was found to be suppressed near GB. [ABSTRACT FROM AUTHOR] |
