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 reported on adding various 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 the hardness value was determined to be 254 HV ± 14. The friction coefficients at 5 and 10 N loads increased by approximately 17.9% and 9.8%, respectively, by increasing the 500 m sliding distance to 1000 m. The effects of strain hardening and brittleness were also observed in the microstructure examinations after the wear test. In addition, a decrease in weight loss was observed, indicating that some deformation hardening occurred in the specimen during wear. [ABSTRACT FROM AUTHOR] |
