对国产EA1N材质车轴疲劳性能进行研究，分别对不同含碳量的EA1N车轴光滑小试样和缺口小试样进行高周旋转弯曲试验，进过107次旋转弯曲循环负载后，试样50%以上试样未有损伤或断裂。含碳量较高的试样疲劳强度更高。
對國產EA1N材質車軸疲勞性能進行研究，分彆對不同含碳量的EA1N車軸光滑小試樣和缺口小試樣進行高週鏇轉彎麯試驗，進過107次鏇轉彎麯循環負載後，試樣50%以上試樣未有損傷或斷裂。含碳量較高的試樣疲勞彊度更高。

Has studied the Fatigue Behavior fo EA1N Axles Steel in the High-Cycle Regime .EA1N axles of different carbon content of smooth specimens and notched specimens of high cycle rotating bending test,After 107 times of rotating bending cyclic load, the sample more than 50% specimens without injury or fracture. Higher carbon content of the sample higher fatigue strength.
