摘要
针对42CrMo筒体锻件冒口端存在的密集型缺陷及超标点状缺陷,对锻件缺陷部位进行了低倍酸浸检验、宏观断口分析、金相分析、扫描电镜分析及能谱分析等。分析结果表明缺陷为大型氧化铝类和氧化钛类夹杂物及夹杂物产生的裂纹,并提出了相应的改进措施。
For the group defects and the unacceptable spot defects appeared on one end of riser for 42CrMo cylinder forgings,the following tests such as macro acid pickling test,macro fracture analysis,metallographic analysis,scanning electron microscopy and energy spectrum analysis etc.have been performed on the defect locations of forgings.The results show that these defects are the large alumina oxide and titanium oxide inclusions and the cracks caused by these large inclusions.Meanwhile,the relevant improvement measures have been proposed as well.
