Notes:
It is important to suppress grain coarsening during the carburizing treatment ofautomobile components such as gears and shafts so that high strength is maintained and heattreatment distortion is minimized. Two manufacturing methods are often used for the cost reduction.One is the increasing carburizing temperature. The other is the adoption of cold forging instead ofhot forging. These methods are likely to result in grain coarsening in the case of conventional steels.It is well known that the key factors to control the grain growth are the initial austenite grain sizeand the volume and mean size of precipitates. In this study, the grain growth property ofTi-modified steel was investigated to confirm the influence of precipitates, and compared with thoseof Nb-modified and conventional steels. The influence of forging temperature on the grain growthproperty in a Ti-modified steel was also investigated
