Fatigue tests were performed using the 3d dumbbell specimens with different levels of maximum strain and hardness.
使用具有不同最大应变和各种硬度的3d哑铃状试样进行了疲劳试验。
The point of intersection of elastic line and plastic line moves toward the low cycle life with the hardness of the spring steel raised after tempering from the strain fatigue curve.
在应变疲劳曲线上，弹性线和塑性线的交点随弹簧钢回火后硬度的升高而向低循环寿命移动；
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。
