Abstract
A novel high wear resistance hypoeutectic Fe-C-B alloy by hot rolling with isolated hard lumps distributed in matrix is reported. The effect of deformation on microstructure and properties of the alloy during hot rolling process was systematically investigated. The results showed that with the increase of deformation, the continuous hard phase network in the alloy was crushed into isolated hard lumps, and the properties of the alloy were improved significantly. The alloy with 66.7% deformation displayed excellent mechanical properties with the impact value of 12.6 J while its hardness was still kept at 58.6 HRC. And the wear resistance of the alloy with 66.7% deformation was 1.21 times as that of the commercial Cr20Mo high chromium cast iron.
