| 摘 要： | 现场观察了双转子断裂的现象，利用LOM及SEM和热处理实验手段发现其断裂属于解理和沿晶复合断裂，断口解理面处大，其组织中有大块自由铁素体和粗大魏氏组织铁素体存在，分析结果表明，此双转子未经热处理就投入使用以及从能谱分析证实其还有一些非金属元素存在是导致该双转子断裂失效的主要原因。

| Abstract: | The phenomenon about fracture of double rotor was observed spottily. The fracture was found to be compound cleavage and Intergranular fracture by means of LOM, SEM and heat treatment instrument. There were massive free- ferrite and widmanstatten structure in big cleavage plane. The experimental analyses results showed that the reason of fracture failure was that because this double rotor was used before heat treatment, the existent non - metal element in samples resulted in fracture failure of double rotor. |
