摘要
利用光学显微镜、扫描电镜、能谱分析仪等对30CrMo钢泵体裂纹形貌和形成原因进行了观察和分析。结果表明:泵体裂纹为相变应力和热应力以及材质冶金质量不高共同作用而产生。
The crack morphology and forming reasons of 30CrMo steel pump body were observed and analyzed using optical microscopy, scanning electron microscopy, energy-dispersive X-ray analysis and chemical composition analysis. The results show that the cracking of the pump body resulted from the interaction of phase transformation and heat stress, as well as the poor quality of metallurgy.
