1. Introduction High chromium hardened white cast iron (HCWCI) is widely used in processes having high mechanical requirements and wear resistance but having limited toughness. Its wear resistance is directly linked to its microstructure and the addition of alloy elements [ 1 ].

The objective of this study is to clad low-carbon steel (LCS) to high-chromium cast iron (HCCI) by using hot rolling process. The results show that the brittle HCCI can achieve plastic deformation when being cladded with LCS. The carbides of HCCI layer were broken, fractured, and refined. However, some carbide pits could be observed between the fractured carbides. The deformation mechanism of

High-chromium cast irons are widely needed by several industrial areas where wear is the dominant environment. They are used in mining, cement- and steel-making plants, and many others. Their microstructure consists of netted eutectic carbides embedded in an austenitic or martensitic matrix. The wear behaviour is mainly controlled by the carbides shape and also matrix type. Several scientific
