Microstructure and wear properties of high manganese steel by V-Ti alloying elements

Abstract High manganese steel was prepared by adjusting the components of the alloys by adding V-Ti. The investigation was carried out to study the effect of V-Ti elements alloying on the microstructure and wear properties of high manganese steel through metallographic microscope, scanning electron microscopy, mechanical machine and abrasive wear tests. The test results showed that V-Ti alloying improved the properties of high manganese steel. The grains are refined, size of impurities are reduced, the form and distribution of impurities are also ameliorated. In addition, the hardness was increased by 23.7%~84.6% and tensile strength can be increased up to 31.3%.
