A new material for abrasion wear resistance, that is, multi-alloyed white cast iron, was developed from the view point of alloy design, solidification structure, solidification sequence, construction of phase diagrams, phase transformation behavior and heat treatment characteristics.
The solidification structure, particularly type and morphology of eutectic carbides, could be controlled in a wide range by combination of alloying elements.
Phase transformation behavior obtained from the CCT curves gave useful instructions to the heat treatment process.
