Abstract: The temperature dependence of critical strain for serrated yielding in high strength A1-Zn-Mg-Cu alloy may be divided into two temperature regions.Their temperature coefficients of critical strain will be negative and positive,respectively.

Key words: serrated yielding, dynamic strain aging, high strength Al alloy, critical strain
