It has been shown that the high cycle and the lowcyclefatiguestrength can be obviously improved by shot peening.
结果指出,喷丸引起表面形变层内的上述变化,能够有效地提高粉末合金高温下的高周和低周疲劳性能。

The factor of life scatter is used for depicting the dispersibility of fatiguestrength in lowcyclefatigue, but in high cycle fatigue is the fatigue strength reduction factor.
低周疲劳常采用寿命分散系数描述结构疲劳强度的固有分散性,而高周疲劳采用疲劳强度减缩系数来描述。

Simple tensile tests and low-cyclefatigue tests under stress control at different temperature were conducted to investigate the effects of temperature on fatigue behavior and fatigue strength.
