PhD position Austenite formation in steel: modelling and experimental validation – Technical University of Delft, Delft (the Netherlands)

////PhD position Austenite formation in steel: modelling and experimental validation – Technical University of Delft, Delft (the Netherlands)

Introduction

The formation of austenite from an initial microstructure of ferrite and pearlite plays an important role in the production of advanced, high-strength steels. However, analysis has shown that the formation of the austenite microstructure is not described accurately enough. It is expected that this is primarily caused by inaccuracies in the nucleation model. Furthermore, in modern practise it happens more and more often that the initial structure before continuous annealing consists of bainite. Therefore, a model that describes austenite formation from bainite must also be developed as part of a through process model for new streel product development. The scientific aim of the project is to extend and experimentally validate the existing cellular automata, sharp interphase, phase transformation model CASIPT by developing (sub-)models that describe the relevant effects of the initial microstructure on the austenite formation kinetics.

Organization

TU Delft’s mission is to make a significant contribution towards a sustainable society for the twenty-first century by conducting ground-breaking scientific and technological research which is acknowledged as world-class, by training scientists and engineers with a genuine commitment to society and by helping to translate knowledge into technological innovations and activity with both economic and social value. The mission of the department of Materials Science and Engineering is to provide internationally recognised, high quality materials research of benefit to industry and society, addressing material lifecycle, structure, properties and functionality from a physics based perspective, and to furnish graduates and post graduates with a top level education in materials science and engineering, preparing them to meet existing and future technological and societal challenges. More information about the research group can be found at https://www.tudelft.nl/en/3me/departments/materials-science-and-engineering/research/metals-and-sustainable-development/

Function

This PhD project forms part of the Digitally Enhanced New Steel Product Development (DENS) program, in which Tata Steel Europe, Materials innovation institute (M2i) and several academic partners collaborate to enable the development of new generations of advanced materials for e.g. the automotive industry.

Digitally Enhanced New Steel Product Development (DENS) program

Significant progress has been made in the past decades in the development of advanced models that describe the behavior of steel during processing and subsequent applications. However, the quantitative application of through process models in new steel product development still lacks predictivity. In modern steel grades, parameters of the steel production process have a significant influence on the final material properties. Furthermore, the trend towards complex multi-phase microstructures requires very sophisticated models to describe their mechanical properties in a predictive manner. The main scientific challenge addressed in this program is to integrate state-of-the-art models in a single through process model framework that can be applied in practice for new steel product development.

The formation of austenite from an initial microstructure of ferrite and pearlite plays an important role in the production of advanced, high-strength steels.
