概要

In order to develop a new eco-friendly non-leaded free cutting steel, it is important to get good machinability by the use of manganese sulfide (MnS) inclusions in place of lead. In this study, the effect of MnS morphology on the surface roughness was assessed in a turning test used two steels containing different type of MnS, and dominant factors controlling the surface roughness were investigated. The distinct type of MnS affected the formation of built-up edge, and it accordingly caused the difference in the surface roughness. This would be based on difference in deformation characteristics of distinct type of MnS.
