High manganese Hadfield steel is the conventional wear-resistant steel. In order to meet the requirements of complex working conditions, Hadfield steel matrix composites (SMCs) with various volume fractions of TiC were designed and fabricated by an in-situ solidification method. The microstructure and abrasive wear properties of these composites were examined. After heat treatment, the composites consist of austenite and TiC phases. TiC particles are uniformly distributed in the matrix, and the interface between the particles and the matrix is clean. Results show that the wear resistance of the composites can be improved by the introduction of TiC particles. However, with the increase of the TiC volume fraction, the wear resistance decreases slightly. We find that the particles increase in size and then their segregations are formed with the increase of the TiC volume fraction. The increased wear rate with the increase of the TiC volume fraction is caused by the fracture of large particles.
