Equal channel angular extrusion (ECAE) was used to deform samples of commercial purity aluminum (AA1050) to a strain of ~8. The effect of extrusion temperature on the deformation microstructures was investigated over the range of 298-523 K. Transmission electron microscopy was used to characterize quantitatively the microstructural parameters, including grain size, shape and boundary misorientation.
Commercial 5052 aluminium alloy was used to study the effect of extrusion temperature on the development of deformation microstructures processed by equal channel angular extrusion (ECAE). The extrusion temperatures used were between 50 and 300 o C, and the cumulative equivalent strain was 5.6. Transmission electron microscopy was adopted to characterize quantitatively the metallographical...
