4th Generation Steels from Phase Transformation Studies - StrainDriven

This project aims to enhance the performance of multiphase steels by characterizing, modeling, and quantitatively describing the microstructure–mechanical property relationships, focusing on solid-state phase transformations. The research aims at optimization of the stability of austenite, a key factor in designing new steels and their practical applications, to improve both strength and ductility. We develop a crystal plasticity model with phase transformations, realistic microstructure, and experimentally calibrated key mechanical and thermodynamic parameters. The research will generate design rules for developing 4th generation advanced high strength steels, modernizing theories concerning strain-induced phase transformations and accelerating alloy development in the steel industry. The outcomes will have a significant impact on metallurgy and steel technology, advancing responsible steel making, and reducing the need for test castings, thus saving time, money, and CO2 emissions.
