    Abstract

    To seek improvements to high stress abrasive wear resistance of titanium carbide composites, the substitution of softer Nickel matrix with a steel matrix having high strength and decent work hardening capability is studied. In order to reveal the characteristics leading to good abrasive resistance of titanium carbide composite with manganese steel matrix observed in experiments, a micromechanical approach is utilized to study the deformation and work hardening behavior of the material. Finite element crystal plasticity model is employed to describe the local behavior of the manganese steel matrix including complex deformation and hardening mechanisms. The microstructure of the material is incorporated using a synthetic microstructure aggregate with carbide and steel phases. The excellent work hardening capability of the composite microstructure results from the grain level hardening of the manganese steel as well as from the interaction with neighboring carbides.
