Patent ID: 7601196

Claim:
A wear resistant sintered alloy consisting of Mo: 5.26 to 28.47 mass %, Co: 1.15 to 19.2 mass %, Cr: 0.25 to 6.6 mass %, Si: 0.05 to 2.0 mass %, V: 0.03 to 0.9 mass %, W: 0.2 to 2.4 mass % and C: 0.43 to 1.56 mass %, and the balance of Fe and inevitable impurities, wherein 5 to 40 mass % of Co base hard phase and 5 to 30 mass % of Fe base hard phase are dispersed in a matrix of a bainite phase or a mixed phase of bainite and martensite, wherein a precipitated material mainly composed of Mo silicide is integrally precipitating in the Co base hard phase, and wherein granular Cr carbide, Mo carbide, V carbide and W carbide are precipitated and dispersed in the Fe base hard phase.
