Effects of titanium content on the microstructure, mechanical properties and wear behavior of the experimental steel were systematically investigated. It was shown that the addition of Ti to the steel resulted in the appearance of granular and short rod-shaped TiC precipitates and long rod-shaped Ti

precipitates. High tensile strength of the experimental steel reached a maximum value of 1276.8 MPa at 0.2% Ti, which represents a 29.5% increase in tensile strength compared to another experimental steel without Ti. With increasing Ti content, the wear rate of the experimental steel showed a trend of first decreasing and then slowly increasing. Following the addition of element Ti, the wear morphology of the experimental steel changed significantly, gradually changing the wear mechanism from one dominated by plough-type abrasives and supplemented by micro cutting to one of plough abrasives.
