• Thirdly, plastic strain ratio and strain hardening index are the two key parameters of material's formability.

  • With the strain aging temperature increasing, strength and hardness increases, plasticity and toughness decreases, yield ratio has the ascending trend, hardening index decreases.

    随着应变时效温度升高强度硬度增加塑性韧性下降屈强比呈升高趋势形变强化指数降低

  • Raising the testing strain rate, the strength and yield ratio increased the plasticity slightly decreased, but the strain rate hardening index kept constant.

    应变增加,材料强度提高,屈强增大塑性略有降低流变阶段应变率强化系数基本不变。
