Abstract

Abstract

In order to explore the mechanism of effect of tellurium modification on the machinability of non-quenched and tempered steel (NQTS), a sulfide modification test of 38MnVS NQTS with tellurium was carried out, and effect of tellurium modification on morphology of sulfide and machinability of steel was compared. The results show that with tellurium addition, the morphology of sulfide in steel is significantly improved, and the aspect ratio of sulfide decreases. Due to the improvement of sulfide morphology after tellurium modification, the cutting force during cutting process is reduced, therefore tool wear is reduced and the generation of chip buildup is prevented as well. Consequently, the workpiece surface roughness is improved, thus improving the cutting performance of NQTS.
