Developing novel heat treatments for automotive spring steels : Phase transformations, microstructure and performance

摘要: This Ph.D. thesis investigates the substitution of quenching and tempering treat- ments by isothermal bainitic treatments in automotive spring production. An treatment has benefits mainly terms energy savings, but it can also prevent quench cracking, distortion residual stresses, commonly found quenched tempered components. A medium carbon low alloy steel employed production is used for this research. The study focuses on microstructure formation its effect performance a component.
