In this study, several deformation twins were found in Al-10.0Zn-3.0Mg-1.8Cu alloy powders after being cryomilled for a certain period of time. Annealing twins were also found in the same powders after they had been cryomilled first and then placed at an ambient temperature for a longer period of time, up to 2years. It is suggested that the Venables model on deformation twins is plausible to explain the twin propensity formed in these powders. The study of the formation mechanism of both deformation and annealing twins concludes that twinning deformation can reduce the grain boundary energy of the alloy powders when the powders are cryomilled first and then placed at the ambient temperature for a longer period of time, up to 2years.
