摘要
针对核电主管道用钢316LN在锻造过程中开裂的现象,借助于金相显微镜(OA)、扫描电镜(SEM)以及能谱仪(EDS)对开裂锻件常温组织以及拉伸断口进行分析。结果表明:脆性氧化铝的大量存在加大了316LN在锻造过程中开裂的倾向。
According to the cracking phenomenon in the forging process of 316LN steel for nuclear power main pipe,with the help of metalloscope(OA),scanning electron microscope(SEM) and energy disperse spectroscopy(EDS),the structure in ordinary temperature and tensile fracture of cracked forging were analyzed.The result shows that the existence of brittle alumina increases the tendency of cracking in 316LN forging process.
