strain hardening rate

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。

The reason for the sawtooth chips is that the adiabatic shear localization occurs in the primary deformation zones when thermal softening exceeds strain and strain rate hardening.

锯齿形切屑产生的原因是第一变形区内因热软化超过应变和应变率强化而发生了绝热剪切局部化。

The pipeline steel with strain-based design is usually characterized by high initial work hardening rate, good ductility, and low yield stress to tensile strength ratio.

抗大变形管线钢就是基于应变设计的方法得到的具有连续屈服、较低的屈强比、较高的加工硬化指数以及均匀塑性变形延伸率等特性的管线钢。
