摘要
为推进连杆裂解材料国产化的发展,通过电镜观察了C70S6连杆材料,探讨了其断口的形貌特征及其化学组成;通过力学试验,研究了该材料的机械性能。结果表明,该材料不仅能够满足连杆的使用要求,在一定条件下还具有断裂低塑性及良好的断裂啮合定位性。
To promote the development of fracture splitting of connecting rod madding in our country, the author discussed the character of fracture morphology and chemical composition of steel C70S6 through SEM and chemical analysis. At the same time, the author investigated the mechanical performance of connecting rod by mechanical experimentation. The result indicates the material not only meets need of connecting rod but also has low ductile fracture and good fracture joggle in definite condition.
