本文通过拉伸及松弛实验,研究了温度和形变速度对材料强度的影响,重点探讨了材料的时温等效关系,并通过电子显微观察,分析了材料形变及断裂过程的特点,断口类型及其影响因素。
In this paper, the effects of temperature and deformation velocity on the strength of materials were studied by means of stretching and relaxation experiments. The time-temperature equivalent relationships of the materials were mainly discussed. The characteristics of the deformation and fracture processes were analyzed by electron microscopy. And its influencing factors.
