working hardening

The results show that trace Cr can enhance Cu Zn alloy hardness and recrystallized temperature in the way of precipitation hardening. Rapid heat rolling and quenching can hold the effects of working hardening, and thermomechanical treatment can develop structure hardening as well.

结果表明：微量Cr能提高Cu Zn合金硬度和再结晶温度，Cr对合金性能的影响是通过沉淀强化来实现的，快速热轧淬火具有保留加工强化的效果，形变热处理还产生了组织强化。

Working hardening modulus and reverse bend curvature in plate hot roller leveling are different obtained.

加工硬化模量和反弯曲率是中厚板在矫直过程中两个关键且难以确定的参数.

Small amounts of silver increase the response to age hardening of the Al-Li-Cu-Mg-Zr alloy used in this study during single aging or double aging, but the effect of silver on the age hardening appears to be decreased by cold working before aging.

在单级时效或双级时效时，Ag明显增加实验合金的时效硬化效果，时效前的预变形减少了Ag对时效硬化的影响。

They can only be strengthened by cold working ( also called strain hardening ).

它们仅可由冷加工增加强度 ( 也叫做冷加工硬化 ).
