摘要 H13(4Cr5MoSiV1)钢是目前使用量最大的一种热作模具钢,钢中夹杂物和碳化物是影响性能及服役寿命的关键因素。实验在Thermo-Calc热力学软件分析基础上,采用金相显微镜、扫描电子显微镜、非水溶液电解装置等装备对某厂H13模铸坯中夹杂物、碳化物的分布规律进行解析。研究表明:夹杂物在H13模铸坯边部至中心,等效直径D≤3 μm的小尺寸夹杂物逐渐减少,D≥5 μm的大尺寸夹杂物逐渐增加,夹杂物的等效直径由2.82 μm增大至3.86 μm,密度由177 个/mm²减少至47 个/mm²,面积占比[0.057%,0.098%];夹杂物类型以MnS和Al₂O₃为主,检测结果与计算结果一致;H13碳化物从边部至心部,形态演变规律为:颗粒状、块状、片状、长条状,尺寸从几微米至100 μm不等;主要为深灰色富V类MC型碳化物、亮白色富Mo类M₆C型碳化物、浅灰色富Cr类M₂₃C₆型碳化物。

Abstract：H13 (4Cr5MoSiV1) steel is one of the most widely used hot-working die steels at present.The inclusions and carbides in steel are the key factors affecting its performance and service life. The distribution law of inclusions and carbides in the H13 die casting billet was analyzed with metallographic microscope, scanning electron microscope and non-aqueous electrolyzer based on the analysis by Thermo-Calc software.The results showed that: from edge to core of H13 die casting billet, the small inclusions with equivalent diameter D≤3 μm gradually decreased, while the large inclusions of D≥5 μm gradually increased. The equivalent diameter of inclusions increased from 2.82 μm to 3.86 μm, the density of inclusions decreased from 177 to 47 PCS/mm², and the area ratio was [0.057%, 0.098%]. The inclusion types were mainly MnS and Al₂O₃, which was consistent with the calculated results. The morphologies of carbides in H13 from edge to core were changed as follows: granular, massive, flake, and long-strip. The size ranged from a few microns to 100 μm. They were mainly dark gray V-rich MC carbides, bright white Mo-rich M₆C carbides, and light gray Cr-rich M₂₃C₆ carbides.

Key words： H13 die steel die casting billet inclusion carbide hot-working die steel
