Notes:
Two commercial Al alloys having different second phase particle distributions weresubjected to severe plastic deformation (SPD) via equal channel angular pressing with or withoutsubsequent cold rolling, and the effect of such SPD on the particle size distribution of the alloys wasinvestigated. The particles larger than ∼ 3 μm were fragmented into several smaller ones by SPD.Contrarily, those smaller than ∼ 3 μm were hardly broken up by SPD but their distribution becamemore uniform. Along with these findings and the theoretical models for cavity nucleation at secondphase particles, the cavitation behavior of ultrafine grained Al alloys during low temperature orhigh strain rate superplastic deformation was discussed
