With the strain aging temperature increasing, strength and hardness increases, plasticity and toughness decreases, yield ratio has the ascending trend, hardeningindex decreases.
随着应变时效温度升高,强度和硬度增加,塑性和韧性下降,屈强比呈升高的趋势,形变强化指数降低。

Thirdly, plastic strain ratio and strainhardeningindex are the two key parameters of material's formability.
塑性应变比与应变硬化指数是评价板料成形性能的两个重要参数。

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