摘　　要：对有效粒子间距，位错弯曲角和位错线张力进行了讨论．通过对过时效，欠时效和有序硬化的沉淀强化合金及对弥散强化的合金的强化机制的定量探讨，分别提出了关于上述合金强化机制的计算模型．Considerable controversy has taken place at present concerning the value of the effective interparticle spacing, the bowing angle of the dislocation and the line tension of the dislocation,etc.. Thus, the different calculation models have been made for the strengthening mechanisms of the particle dislocation interaction. This paper quantitatively researchs the strengthening mechanisms of the overaged, underaged and order hardened precipitation strenthening alloys and dispersion strenthening alloys. The more accurate calculation models of the strengthening mechanisms for the above alloys have been given respectively.
