    摘要： A sintered material for valve guides consists of, by mass %, 1.3 to 3 % of C, 1 to 4 % of Cu, 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 carbide phase, and a copper phase, and a part of the pores includes graphite that is dispersed therein. The iron carbide phase is dispersed at 3 to 25 % by area ratio and the copper phase is 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 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 material for valve guides consists of, by mass %, 0.01 to 0.3 % of P, 1.3 to 3 % of C, 1 to 4 % of Cu, 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 a copper phase, and a part of the pores including graphite that is dispersed therein. The iron-phosphorus-carbon compound phase is dispersed at 3 to 25 % by area ratio, and the copper phase is dispersed at 0.5 to 3.5 % by area ratio, with respect to a cross section of the metallic structure, respectively.
