Abstract
Polycrystalline aluminium samples have been uniaxially compressed to true strains of 0.22 and 0.51 at 300 and 400-degrees-C for each true strain. The hot deformed samples were quenched to room temperature. The deformed microstructure has been studied by using the Transmission Pseudo-Kossel X-ray microdiffraction technique to measure the orientational changes within the deformed grains. The disorientation across the transition bands and the degree of orientational spread within the deformed grains increased with the amount of deformation. Transition bands have identified by a split of the poles spread on stereographic projections of the deformed grains. Taylor's postulate for compression texture for f.c.c. metals has been confirmed for aluminium samples hot-deformed. The compression axis plot showed the rotation of matrix grains away from the unstable and orientations toward the stable orientation.
