讨论了金属塑性变形的动力学性质及其与特定热激活位错机制的关系。描述了用于评估识别速率控制位错机制所需的变形参数的实验技术。列出了在不同温度范围内控制的机制。热活化过程的力距曲线、位错扭结或微动的能量、堆积断层能和自扩散的活化能等基本晶格性质均可由宏观力学性能数据导出。
The dynamic nature of the plastic deformation of metals and its relation to specific thermally activated dislocation mechanisms are discussed. Experimental techniques for evaluating the deformation parameters needed to identify the rate-controlling dislocation mechanism are described. The mechanisms that appear to be controlling in various temperature ranges are listed. Such fundamental lattice properties as the force-distant curve for a thermally activated process, the energy of a dislocation kink or of a jog, the stacking-fault energy, and the activation energy for self diffusion are indicated to be derivable from macroscopic mechanical property data.
