摘要： A wear resistant sintered member exhibits superior wear resistance at the same level as those of the conventional materials without using a Co-based hard phase is provided. A first hard phase comprising Mo silicide particles dispersed in an Fe-based alloy matrix of the first hard phase and a second hard phase comprising a ferrite phase or a mixed phase of ferrite and austenite having a higher Cr concentration than the Fe-based alloy matrix surrounding a core consisting of Cr carbide particles, are diffused in an Fe-based alloy matrix, the Mo silicide particles are contained in the first hard phase in an amount of 3 to 25% by area, and the Cr carbide particles are contained in the second hard phase in an amount of 3 to 30% by area.
