结果表明:半固态加工试样300℃以下拉伸,表现出高强度、低塑性特征,400℃以上拉伸两种加工方法的强度和塑性非常接近;半固态高温断口特征表现为韧性断裂,宏观断口存在明显的二次裂纹。
3) Brittle fracture
脆性断口
4) ducile fracture,plastic fracture
塑性断口
5) tough fracture
韧性断口

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。
补充资料：杯锥断口
cupconefracture：圆柱形拉伸试件于延性断裂（韧性断裂）后，一侧的断口呈杯状，另一侧的断口呈锥状，两者合称杯锥断口。
