softening

The testing involved Comprehensive thermal analysis loading softening performance.

测定内容包括对南钢烧结矿试样的综合热分析和烧结矿荷重软化性能的测定。

Numerical analysis indicates that strain hardening and strain rate hardening are to resist the growth of voids, whereas the ambient temperature is to promote the growth of voids in OFHC. It is also shown that the thermal softening has negligible influence on the growth of voids.

模型的数值分析表明，对OFHC铜来说，应变硬化效应、应变率效应阻碍了孔洞的增长，热效应对孔洞增长影响不大，而环境温度的升高促进了孔洞的增长。

In the current model of cutting force, Oxley model is the one which considers the material properties comprehensive mostly. However, the material strain rate effects and thermal softening effects are still considered less than.

目前所得到的切削力模型中，Oxley模型相对来说是考虑材料性能最全面的，但是对于材料的应变速率效应及热软化效应考虑不足。
