Synopsis :The influence of alloying elements on microstructure and wear resistance of High Speed tool Steel roll (HSS roll) was studied in order to improve wear resistance and surface deterioration resistance of HSS roll. Although the volume of eutectic M7C3 carbide increased with the increase in C and Cr contents, wear resistance was not improved. The increase in Cr and Mo contents in good balance improved the wear resistance of HSS Roll remarkably, as eutectic carbide of M7C3 type became tough and the damage on the worn surface was prevented.The destructive prevention mechanism of carbide was discussed from change of the alloy concentration and the lattice constant of carbide by increasing in Cr and Mo contents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
