This paper has an analysis on the fracture feature of the connecting rod bolt from the aspect of fractography and material structure and its corresponding property after observing and analyzing the fracture of the connecting rod bolt with the SEM and the AES;and proposes that overloading and over impurity for a connecting rod bolt will lead to tough fracture.
对某轮柴油主机损伤的连杆螺栓断口进行扫描电镜观察和能谱仪分析,从断口形貌学和材料组织与性能的角度对螺栓断口形貌特征进行了研究,指出这是一种因过载和材料中杂质过多引起的韧性断口。

The results indicate that the impact energy of alloy GH4169 decreases as the area percentage of δ phase concentration zone in microstructure increases, and the impact fracture are of dimple surfaces.
对ＧＨ４１６９合金中的δ相密集区所占的面积分数与冲击功的关系进行了定量研究，并用ＳＥＭ观察了冲击断口的表面，结果表明：ＧＨ４１６９合金的冲击功随组织中δ相密集区所占的面积分数增大而减小，冲击断口为韧窝断口。

%Ni shape memory alloy with SEM; We find dimples and tearing slits on the surface.
59%(原子分数)Ni形状记忆合金用扫描电镜(SEM)观察了其断口组织形貌,发现了韧窝、撕裂带,认为该合金具有一定的韧性;用透射电镜(TEM)观察了合金的内部组织结构,发现了位错塞积、形变亚晶界、马氏体片以及孪晶,认为位错对合金的马氏体相变具有重要的作用,马氏体间的应力集中将产生微裂纹。
