摘要：
The main aim of the paper is to estimate the deformation mechanism of the high-temperature deformation in the Al-Zn-Mg-Cu alloys (V95 and ONZ 42 4222). The results of tensile tests, especially of the measurement of strain rate sensitivity parameter m are given. The structure changes observed using light and transmission electron microscopy are documented. The phenomenological model based on the concept of a threshold stress is tested.
