论文摘要
这篇综述是热力学错位理论的简化摘要，特别强调了有效温度的作用。数十年来，材料科学家断言统计热力学不适用于脱位。通过使用简单的，第一原理的分析和与实验数据的比较，我认为这些科学家是错误的，并且由于其广泛的基本和技术重要性，因此迫切需要将这种古老的领域恢复活力。除了描述理解应变硬化，屈服，剪切带等方面的最新进展外，我认为热力学脱位理论还可以导致对晶体固体中脆性和延性骨折的急需，第一原理的理解。
This review is a simplified summary of the thermodynamic dislocation theory, with special emphasis on the role of an effective temperature. Materials scientists, for decades, have asserted that statistical thermodynamics is not applicable to dislocations. By use of simple, first-principles analyses and comparisons with experimental data, I argue that these scientists have been wrong, and that this venerable field urgently needs to be revitalized because of its wide-ranging fundamental and technological importance. In addition to describing recent progress in understanding strain hardening, yielding, shear banding, and the like, I argue that the thermodynamic dislocation theory can lead to a much needed, first-principles understanding of brittle and ductile fracture in crystalline solids.
