Inverse design of dual-phase steel microstructures using generative machine learning model and Bayesian optimization

International journal of plasticity, 2023
The design of optimal microstructures requires first, the identification of microstructural features that influence the material’s properties and, then, a search for a combination of these features that give rise to desired properties.

Coupled heat transfer and phase transformations of dual-phase steel in coil cooling

Materials Today Communications, 2021
Dual-phase steels are generally used in the car industry due to high tensile strength and good formability, which are obtained by a mixture of bainite and ferrite phases. This microstructure is achieved through slow rate coil cooling.
