摘要： A sintered material for valve guides consists of, by mass %, 1.3 to 3% of C, 1 to 4% of Cu, 0.01 to 0.08% of P, 0.05 to 0.5% of Sn, and the balance of Fe and inevitable impurities. The sintered material exhibits a metallic structure made of pores and a matrix. The matrix is a mixed structure of a pearlite phase, a ferrite phase, an iron-phosphorus-carbon compound phase, and at least one of a copper-tin alloy phase and a combination of a copper phase and a copper-tin alloy phase. A part of the pores includes graphite that is dispersed therein. The iron-phosphorus-carbon compound phase is dispersed at 3 to 25% by area ratio, and the copper-tin alloy phase and the combination of the copper phase and the copper-tin alloy phase are dispersed at 0.5 to 3.5% by area ratio, with respect to a cross section of the metallic structure, respectively.

摘要： A sintered valve guide exhibits a metallic structure having a mixed structure and a hard phase in which hard particles are dispersed in an alloy matrix. The mixed structure consists of pearlite, an Fe—P—C ternary eutectic phase, a ferrite phase, a copper phase, and pores, and the mixed structure consists of, by mass %, 0.075 to 0.525% of P, 3.0 to 10.0% of Cu, 1.0 to 3.0% of C, and the balance of Fe and inevitable impurities. The hard phase is dispersed at 2 to 15 mass % in the mixed structure.
