Study on Residual Stress in Cylinders Generated by Quenching, Fourth Report: Prediction for Stress Reduction by Tempering after Quenching

円柱の焼入れにより生じる残留応力について

In this research, the numerical analysis method which can predict the residual stress distribution after tempering with sufficient accuracy was established. First, residual stress distribution of the cylinders test material after quenching and tempering was measured. Next, the creep test was done using the material after quenching, and the formula which predicts the creep strain of each material was clarified. Finally, comparison and examination of the experimental and numerical analysis value of the residual stress distribution after tempering was performed using the formula which predicts creep strain drawn from the experiment. By using the linear expansion coefficient, the yield stress of heating and cooling process of tempering, and the formula which predicts the creep strain, the residual stress distribution after tempering can be predicted with sufficient accuracy by numerical analysis. Moreover, reduction of the stress by tempering has the great influence by the fall of yield stress and creep strain, and the influence of strain resulting from a deposit of the carbide which arises in the heating process of tempering hardly affects residual stress distribution.
