What is AA2618 and AA7075 alloys superplastic transition in isothermal hot-deformation tests about?
This work deals with the isothermal deformation behaviour of two aluminium alloys, AA2618 and AA7075. These materials Ž . were integrated by mechanical tests, differential thermal analysis DTA , and metallographic examination. Stress᎐relaxation and compression tests confirmed that both alloys exhibit a superplastic behaviour, characterised by a large elongation before failure and at low flow stress. Ranges of temperature and strain rate, at which such a superplastic behaviour is predominant, are shown. In particular, temperatures at which the strain-rate sensitivity parameter m is higher than 0.7, as determined by the isothermal stress᎐relaxation tests, are defined. Finally, the relationship between the results of deformation tests and microstructural properties is discussed, considering the perspectives of utilising these alloys for industrial isothermal forging.
