    摘要： A sinter-joining method for forming a sinter of high quality at low cost and a sintered composite member produced by the sinter-joining method.A tubular copper-base material is forced into a tubular iron-base material and these materials are sintered at temperatures equal to and higher than 600.degree. C. so that the copper-base material expands and pressure-joins to the iron-base material. Then, the materials are sintered at temperatures equal to and higher than 850.degree. C. so that the compactness of the copper-base material is increased. Through these steps, the sintered composite member containing the copper-base material joined to the inside of the iron-base material is obtained.

    摘要： Quenched layers are formed without irregularities on the inner circumferential surface of a track bushing having a small inside diameter or on the inner circumferential surfaces of two or more track bushings which are subjected to quenching in an overlapped condition. To introduce a cooling medium for cooling the inner circumferential surface of the track bushing, a guide tube having an outside diameter smaller than the inside diameter of the track bushing is disposed on the side of the inner circumferential surface and the cooling medium introduced by the guide tube is diverted by a diverting member having a spherical or similar curved surface, such that the cooling medium is allowed to flow in a direction substantially parallel with an axial direction of the track bushing 1 within a space defined by the outer circumferential surface of the guide tube and the inner circumferential surface of the track bushing, thereby performing laminar flow cooling.

    摘要： The pitting resistance of a gear is increased by hardening its tooth flanks through application of carburizing/quenching, bright hardening and induction hardening to a steel material capable of providing significantly improved softening resistance in tempering at a low temperature of 300 to 350° C. To this end, the steel material prepared so as to satisfy the relationship described by: 5≦4.3×Si(wt %)+7.3×Al(wt %)+3.1×V(wt %)+1.5×Mo(wt %)+1.2×Cr(wt %)×(0.45÷C(wt %)) is carburized such that the carbon concentration of its carburized surface layer is adjusted to 0.6 to 0.9 wt %; and the steel material is subjected to quenching and tempering at 300° C. or less subsequently to the carburization process, or alternatively the steel material is once cooled after the carburization process and then subjected to treatments of re-heating hardening and tempering at 300° C. or less so that a hardness of HRC 58 or more is ensured by the tempering process at 300° C.
