摘要
通过金相显微镜、扫描电镜等对PCrNi3MoVA电渣钢锻材断口中部异常形貌进行了研究.结果表明,石状断口不仅分布在钢材的边部、棱角处,而且还可能在钢材的中部产生.
By means of optical metallograph and SEM > the abnormal morphology in the fracture centre of PCrNi3MoVA ESR steel forgings was studied. The results show that the stone-like fracture morphology appears not only at the edge of the fracture surface but also in the centre of the fracture.
