摘要

本研究利用斑点摄影技术研究了纯铝多晶体的塑性变形定位规律。研究表明，在 170 < T < 350 K 温度范围内的抛物线加工硬化阶段，温度对静止耗散结构出现的影响取决于宏观层面局部塑性自波长度的变化和微观层面位错子结构的晶胞尺寸。

On the Thermally Activated Changes in Autowave Parameters of Localized Plastic Flow

In this work, plastic deformation localization regularities in pure aluminum polycrystals are studied using speckle photography technique. It is shown that at the parabolic work hardening stages in the temperature range of 170 < T < 350 K, the temperature effect upon the emergence of a stationary dissipative structure is determined by the change in the autowave length of localized plasticity at the macroscale level and the cell size of the dislocation substructure at the microscale level.
