Extensive hot deformation was performed on three white cast irons having different carbon contents. The mechanism of formation of ledeburite eutectic during plastic working was investigated. It wasfound that white irons can undergo hot forging, hot rolling, and warm rolling at 700°C–1100°C. The refinement of massive carbide occurs by the combined contributions from plastic working and diffusion of carbon atoms. The structure of worked cast iron consists of small cementite particles distributed in a fine ferrite matrix.
