6. Conclusions
- Transformation plasticity reflects an important distortion behavior of alloy steel materials during the carburizing and quenching heat treatment process. To reveal the densification behavior and material properties of transformation plasticity, the method proposed in this paper for the precise measurement of distortion behavior under rapid cooling is a very effective and practical experimental technique.
- The behavior of transformation plasticity is essential to predict component distortion and residual stresses after carburizing and quenching and to improve the accuracy of heat treatment simulations.
