| Scope |
In recent years, A comprehensive understanding has been reached regarding research, development, design, and processing of novel 3rd generation high/ultrahigh strength steel concepts with excellent combinations of properties. Various research themes including Q&P steels, nanostructured bainitic steels and medium-Mn steels, have been identified and developed, often in combination with multidisciplinary research. To create sustainable steels several times stronger than conventional steels, significant weight reductions are needed for realizing lightweight structures, thus moving towards carbon-neutral society by lowering of greenhouse gases. Recent advances in the understanding of steel science using multiscale research have clarified how atoms can be arranged in hot-rolled structural steels to obtain high levels of strength together with high fracture toughness, wear resistance and usability properties. Engineered microstructures in these advanced steel concepts normally comprise two or more phases, often finely divided to nanometer level with various functionalities and require advanced physical and numerical modelling for the predictions of structure-property relationships. The key identified areas include studying the structural refinement, morphology of phase constituents, kinetics of phase transformation and structural mechanisms for the novel steel concepts using advanced metallography as well as analytical techniques, besides understanding the fracture mechanisms of these complex microstructures. This symposium focusses on recent advances in the development and processing of 3rd generation steels, encompassing various research themes and future plans envisioned to meet the strategic goals of carbon neutral future. |
