Microstructure and Deformation Characteristics of MNS in 1215ms Steel at 1050oc

In this study, the deformation behavior of manganese sulfide in 1215MS steel was investigated during thermomechanical process. The microstructure has been characterized by optical microscopy (OM), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), and electron backscattering diffraction (EBSD). As increasing the reduction in thickness from 10% to 70%,the average aspect ratio was increased from 1.20 to 2.39. In addition, the deformability of MnS inclusion is smaller than the matrix. The possible slip systems of A, B, C, and D plane traces were(1 􀴤 01􀴤 )[1 􀴤 01], (101􀴤 )[101], (011)[011􀴤 ], and (110)[11􀴤 0]. Furthermore, the EBSD measurements suggest that the slip plane in MnS inclusions occurs on {110} planes. Keywords- Manganese sulfide, Inclusion, EBSD, KAM
