INVESTIGATION OF MICROSTRUCTURE AND WEAR PERFORMANCE OF THE HIGH MANGANESE STEELS
Abstract
High manganese steel is a metallic material that has a very important commercial value especially in heavy industry and stands out with its features such as high wear resistance and deformation hardening. In order to further improve the properties of these steels, many studies have been reported on adding different elements to their structures. However, there is still a lack of understanding of the relationship between the wear mechanism and strain hardening due to changes in the microstructure of high manganese steel during the wear process and the complex carbides it contains. In this study, Al5Ti1B (1% wt.), which is also used as a grain refiner in the metallurgy industry, was added. After melting, casting and other production processes, test samples were prepared for microstructure analysis, hardness and wear tests. It was observed that there were carbide phases at the grain boundaries of the test sample and it was understood that the hardness value was 254 HV +/- 14. In addition, a decrease in weight loss was observed, indicating that some deformation hardening occurred in the specimen during wear.
