摘要
在大量实验的基础上,对国产43C_iN_i2M_0VA钢的超高压泵阀箱材质疲劳断裂性能进行了研究。并探讨了超载对疲劳裂纹的萌生寿命以及裂纹疲分扩展速率的影响。
On the basis of a lot of experiments, we researched on the fatigue fracture properties of of 43CrNiZMoVA steel used for super high pressure pump's flud end, and discussed the influence of overload on the forming life and progress of fatigue crack.
