How sell the metal forms will be governed by the strain - hardening exponent and average strain ratio.

如何选模由加工硬化指数和平均应变比例所决定.

At the end of the plateau, strain - hardening begins, with a subsequent increase in strength.

在平稳段结束后, 强化阶段开始, 并伴随着强度的持续升高.

Because they interfere with the movement of dislocations, grain boundaries also influence strain hardening.

因为它们可以阻止晶粒随意的运动,同时晶界还可以影响加工硬化.

However, all elements beyond the strain - softening region were always in a state of strain hardening.

在加载中, 由于增加的围压力使一些应变软化单元回到应变硬化状态.
