A sigmoidal reletionship was observed between stmin r&e and stress in the Zn-22 % Al euteotoid alloy, dividing the behavior into three distinct regions. At high strain rates (region III), the activation energy was similar to that, anticipated for lattice diffusion, and the results support the sugges
