Shape accuracy of steel gears and shafts depends on the heat treatment distortion in the oil quenching condition of those parts. The distortion is mainly caused by the inhomogeneous cooling in oil quenching. The deformation by heat treatment can be e

It is known that austenite grain coarsening during carburizing is likely to occur in cold-forged steel parts. For efficient use of this production process, it is important to clarify the mechanism of grain coarsening. In this study, mechanism of aust

Steel bars and billets may have center porosities caused by contraction during castng. It is important to optimize not only casting conditions but conditions of subsequent forging and rolling in order to decrease the center porosity.Forging and rolli
