Al-Zn-Mg-Cu alloy with different crystallite size is prepared by mechanical milling and high temperature consolidation. X-ray line profile analysis and HRTEM image show high temperature consolidation results in insignificant grain coarsening. Microhardness of the alloy as a function of crystallite size shows break down of Hall-Petch relationship. (C) 2016 The Society of Powder Technology Japan.
