PostDoc position Reclaiming valuable metals in HIsarna ironmaking process – pneumatic injection – Technical University of Delft, Delft (the Netherlands)

December 14th, 2017|Categories: Modeling & Simulation, PostDoc, Vacancies|Tags: , , , |

Introduction ReclaMet is an up-scaling project funded by EIT Raw Materials. This project aims for enriching the zinc content in the HIsarna flue dust to the level which makes it suitable for use in Zn smelters as secondary raw materials. The project is led by Tata Steel R&D in IJmuiden, Netherlands, with partnership of TU Delft, CRM, and Nyrstar.The HIsarna process is a new and ground-breaking smelting reduction process for the production of liquid hot metal from iron ores and coal. The main driver to develop this process is the need for an ironmaking process with a significantly reduced carbon

PhD position Prediction of local material response to welding – Technical University of Delft, Delft (the Netherlands)

Introduction The design requirements of new steel grades for the automotive industry are driven by the targeted application. Optimised strength-formability properties are often the first design objective. Nevertheless, other properties, such as fatigue strength, edge ductility or weldability have gained increased attention the last years, since improved strength-ductility performance often comes at the cost of decreased fatigue, edge ductility or weld behaviour. Currently, weld testing can be done only in the later stages of material development, when larger quantities of a trial material are available. In order to capture potential problems as well as solutions for acceptable weld behaviour in

PhD position Continuum modelling of recrystallization textures during CA – Technical University of Delft, Delft (the Netherlands)

December 14th, 2017|Categories: Modeling & Simulation, PhD, Vacancies|Tags: , , , |

Organization The Department of Materials Science and Engineering (MSE) of the Delft University of Technology, undertakes coherent and innovative research dedicated to developing, producing, characterising and manipulating materials, with a focus on metals. The aim is to develop fundamental understanding forming the basis for better performance, a longer life cycle with preservation of functionality, while at the same time optimising sustainable use of resources and minimising environmental footprint.The Mechanical Behaviour group performs research on the mechanical properties depending on microstructure and texture, consolidation and failure mechanisms in relation to industrial applications.

PhD position Multi-field RVE simulation – Max Planck Institute Düsseldorf (Germany)

December 14th, 2017|Categories: Modeling & Simulation, PhD, Vacancies|Tags: , , , |

Introduction Microstructure evolution during a processing chain can be described on the basis of a (small) number of physical processes. The most important ones being strain hardening, transformation, recrystallization and precipitation. For all of these individual processes models have been developed in the past that can describe them rather well. However, to date most of these models concentrate on one individual aspect of microstructure evolution, while neglecting all others. In contrast to this, many of these processes appear in a concurrent way during the processing chain. Only very recently simulation frameworks have become available that allow solving multi-field problems.

Introduction Digitally Enhanced New Steel Product Development (DENS) programSignificant 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 and therefore faces a number of scientific challenges. 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. Accordingly, a through

PhD position: Edge ductility of AHSS in relation with localization and damage – University of Twente, Enschede (the Netherlands)

December 14th, 2017|Categories: Modeling & Simulation, PhD, Vacancies|Tags: , , , , |

Introduction It is commonly observed in steels with complex microstructural features, such as AHSSs, that the macroscopic observed behaviour in many aspects are different compared to conventional materials. What is relevant for this project is the Edge Ductility property of these materials measured generally in terms of the hole expansion capacity (HEC). AHSSs show highly sensitive results to the geometry used for determining the HEC that means that the definition of this property is incomplete. Therefore one of the goals is to establish a set of well-defined experiments with which a material dependent (but compensated for geometry and structure of

PhD position: Effect of Retained Austenite on macroscopic material behaviour – University of Twente, Enschede (the Netherlands)

December 14th, 2017|Categories: Modeling & Simulation, PhD, Vacancies|Tags: , , , , |

Introduction In steels with complex microstructures where especially multiple phases and mechanically induced transformations exist the macroscopic mechanical behaviour is observed to be sensitive to microscopic phenomena. Some of the observations include (but not limited to) damage sensitivity to phase contrast and ductility dependence on retained austenite phase. Although the observed phenomena are explained in detail in their respective scales this project aims to make this information usable in the scale where industrial products are simulated. Most of the phenomena relate directly to the production process where the amount and morphology of the phases can be controlled by the heat

PhD position Statistical Interpretation of microstructures – Technical University of Delft, Delft (the Netherlands)

December 14th, 2017|Categories: Modeling & Simulation, PhD, Vacancies|Tags: , , , |

Introduction For Through Process Modelling, the study of microstructural properties in steels is crucial. Microstructural quantities of interest include grain size, particle size, grain shape, grain orientation and grain mis-orientations, spatial distributions and anisotropy. Using in-house characterization techniques at TATA steel, profiles of 2D-sections of 3D samples can be obtained. Extracting information on the 3D features based on the 2D pictures, is a stereological problem. An essential step in this process is to describe the formation of microstructures using a realistic well defined stochastic model. Then, the “direct problem” needs to be solved, expressing the stochastic behaviour of the 2D
