Abstract

Abstract

A compression test was conducted via a Gleeble-1500 thermo-mechanical simulator. The effects of different deformation temperatures and deformation on the size and relative plasticity of MnS inclusions in steel were studied. It is found that fragmentation and growth of MnS occurred alternately during the deformation process, and the temperature and the deformation greatly influence the size of MnS. With the increase of deformation, the quantity of MnS with an aspect ratio of less than two decreases first and then increases. The relative plasticity shows a trend to decrease at low temperatures. Nevertheless, the quantity and relative plasticity of MnS changed oppositely when gear steel was deformed at high temperatures. Choosing large deformation at low temperature or small deformation at the high-temperature rolling system in actual production can obtain many MnS inclusions with a small aspect ratio.
