The transition from discontinuous to continuous recrystallization in some aluminium alloys I - the deformed state

Journal Article · · Acta Materialia
The microstructures developed during deformation to large rolling strains in single and two-phase aluminium alloys with a wide range of grain sizes has been investigated, and the major parameters of the microstructure determined by high resolution electron backscatter diffraction (EBSD). It is found that the behaviour of initially fine-grained (<5 {mu}m) alloys is significantly different from that of the large-grained (>50 {mu}m) alloys. In the finer-grained alloys no significant grain fragmentation occurs, and at larger strains, when the spacing of high angle boundaries approaches the crystallite size, a considerable amount of the high angle boundary is removed by a process of dynamic recovery.
