evolutions of two Al-Zn-Mg alloys, one of which was alloyed with Sc and Zr, and the kinetics of Al3(Sc1-xZrx) precipitates in the Al-Zn-Mg alloy during homogenization were investigated. Both alloys under as-cast condition with supersaturated, non-equilibrium T(Mg32(Al, Zn)49) phase and impurities phase were displayed. When the homogenization temperatures are below 350 °C, Zn and Mg atoms precipitate......
