摘要
采用金相检验、扫描电镜检验等手段对DH36船板钢拉伸断口分层缺陷进行了分析。结果表明:DH36船板钢拉伸断口分层缺陷主要是由钢板厚度中心条状MnS夹杂和宽大的贝氏体、马氏体带状组织引起的。
The reasons for the laminated fracture under tensile test of DH36 hull plate were researched by metallurgical observation and SEM observation. The results show that the main reasons are the aggregation of MnS as well as the martensite and bainite banded structure in the center of plate.
