Abstract

The creep response, mechanical properties, and microstructure evolution of the Al-Zn-Mg-Cu alloy were investigated under different initial heat treatment conditions. The results indicate that the density of geometrically necessary dislocations (GNDs) increases during the initial creep stage (
