| Abstract | The effects of carbon content on the microstructure, mechanical property, wear resistance and corrosion resistance of Mn8Cr2Si steel was investigated . The change of austenite grain size was observed by optical microscope (OM). The impact fracture and wear morphologies were analyzed by scanning electron microscopy (SEM). The results indicate that the austenite grain becomes refinement with the increase of carbon content. Nevertheless, when the carbon content is over 0.8%, the grain starts to be coarse. Due to the refinement of the austenite grain, the total area of grain boundaries increases and the stress concentration is reduced, which suppress the formation and propagation of cracks. Therefore, the finer the austenite grains, the better the mechanical property is, and the upgrade of mechanical property will help to improve the wear resistance of Mn8Cr2Si steel. It is found that the austenite grain size also affects the corrosion resistance of Mn8Cr2Si steel, and the corrosion resistance can be improved with the refinement of austenite grains. When the carbon content of Mn8Cr2Si steel is 0.8%, the grain size can be refined to be 143 μm, and the composite mechanical property and the corrosion resistance are excellent. |
