Respond of structural changes on deformation behaviour of ECAP processed aluminium alloy AA7075
Original language description
In order to improve the deformation behaviour of SPD prepared aluminium alloy AA7075 microstructure modification by ageing due to various holds at precipitation temperature prior to ECAP processing and post-deformation treatment were carried out. Over-aging process carried out prior severe deformation modified the characteristics of precipitates (intermetallic phases) present in alloy. The microstructure refined by intensive deformation was then altered by various annealing procedures. Ageing prior to ECAP contributed to a small increase in strength, as hardness results, as shown by results of hardness measurement and observation of microstructure. On the other hand, post-deformation annealing of the ECAP-ed samples at various temperatures markedly modified the deformation response of the alloy as regards ductility. Evaluating the mechanical properties a small increase in strength was achieved at lower temperature of at lower temperatures of annealing (250°C, 300°C), whereas the highes
