The fatigue-crack growth of the die-forged Al-5.87Zn-2.07Mg-2.42Cu alloy at different ageing conditions: peak aged (T6), over aged (T73) and retrogression and re-ageing (RRA), has been examined in the study. The RRA alloy has the highest resistance t

An approach combined the enhanced solution treatment (EST) and the non-isothermal ageing (NIA) treatment was employed on the as-rolled Al-Zn-Mg-Cu alloy. The hardening response is greatly affected by the precipitates size distribution and their volum
