摘要
测试和分析结果表明:非高温扩散-超细化的H13(4Cr5MoSiV1)钢材存在大块状的共晶碳化物,带状偏析严重,钢的横向冲击韧性较差;而经过合理的高温扩散和超细化处理的H13钢材,共晶碳化物基本消失,带状偏析和组织均匀性明显改善,显著提高钢的横向冲击韧性。
Results of examination and analysis indicated that in normal non high temperature diffused-superfining treated H13 (4Cr5MoSiV1) steel products there were massive euteetie carbides with serious banding segregation and transverse impact toughness of steel was lower; and in available high temperature diffused and superfining treated H13 steel preduets, the eutectie carbides were basically dismissed, the banding segregation and structure homogeneity improved obviously and the transverse impact toughness of steel increased appreciably.
