Partial dislocation emission in a superfine grained Al–Mg alloy subject to multi-axial compression

We report partial dislocation emission from subgrain boundaries with subgrain size being significantly larger than 100nm in an Al–Mg alloy. The dislocation density in subgrain boundary has significant effect on partial dislocation emission. The high stacking fault density inside a subgrain is relate...

Summary:We report partial dislocation emission from subgrain boundaries with subgrain size being significantly larger than 100nm in an Al–Mg alloy. The dislocation density in subgrain boundary has significant effect on partial dislocation emission. The high stacking fault density inside a subgrain is related to the large dislocation density in the subgrain boundary.
