Abstract A 304 stainless steel/medium carbon steel clad plate was fabricated by hot-rolling in an argon atmosphere. The interfacial microstructures of the clad plates were observed by SEM, and the carbide phases were identified by XRD and TEM. The effect of the rolling parameters on the shear strength and composition diffusion was analyzed. The results show that a sensitization region appears in the stainless steel side and a decarburization region is present in the carbon steel side. The sensitization region is composed of a dual structure, ditch and full-depletion of chromium zones. The precipitates in the stainless steel side are Chromium-rich M23C6 carbides.

轧制不锈钢/中碳钢复合板的显微组织与性能

摘要 在氩气气氛中通过热轧制备了304不锈钢/中碳钢复合板。通过SEM观察复合板的界面微观结构，通过XRD和TEM鉴定碳化物相。分析了轧制参数对剪切强度和成分扩散的影响。结果表明，不锈钢侧出现敏化区，碳钢侧出现脱碳区。敏化区由双重结构、沟渠和全耗尽铬区组成。不锈钢侧的析出物为富铬M23C6碳化物。
