摘要： A reduced-pressure heat treatment jig is used for supporting a workpiece of iron when the workpiece is subjected to heat treatment in a reduced-pressure atmosphere in which pressure is reduced compared to atmospheric pressure. The jig is formed of an iron material and is formed with a film on at least a contact surface with the workpiece, the film being formed of a material which persists during the heat treatment. The film preferably includes a metal oxide having an evaporating temperature higher than the heat treatment temperature in the reduced-pressure atmosphere. The film preferably contains aluminum oxide.

摘要： The present invention provides a method for induction hardening of a steel member having an outer ring portion and, more specifically, for induction hardening of an outer circumferential surface of the outer ring portion. The method uses two pressing members, each of which includes a flat basal surface and a projecting portion projecting therefrom. Each of the projecting portions has a cross-section in the shape of a perfect circle. Also, the projecting portions have, on the outer circumferences thereof, respective pressing surfaces. While gaps are maintained between axial end faces of the outer ring portion and the basal surfaces of the pressing members, the pressing members are pressed against the outer ring portion so that the pressing surfaces each abut against the inner circumference side of the outer ring portion. While a biasing force is applied to the pressing members, the induction hardening process is applied to the outer circumferential surface. During the induction hardening process, the pressing members are moved toward each other until the basal surfaces abut against respective axial end faces of the outer ring portion.

摘要： A method of carburizing and quenching a steel member includes: a reduced pressure carburization step in which a steel member is contacted with carburization gas under reduced pressure, a slow cooling step in which the steel member is then slowly cooled in a cooling gas, and a quenching step of heating a selected portion of the cooled steel member using high-density energy and subsequently subjecting the selected portion to rapid cooling. The steel member subjected to the low-pressure carburization step includes a first portion in which a diffusion rate of carbon taken therein during carburization is high because of its shape and a second portion in which the diffusion rate of carbon is lower than that of the first portion. The reduced-pressure carburization step is controlled to give a carbon concentration at the surface of the first portion in a range of 0.65±0.1 weight % after diffusion.
