Researcher · RWTH Aachen University · company speakers →

Bengt Hallstedt studied physical metallurgy at the Royal Institute of Technology in Stockholm, Sweden. As a freshly graduated engineer he spent three years at AB Sandvik Steel developing high temperature steels. After that he returned to Stockholm for doctoral studies in physical metallurgy where he learned Calphad modelling under the guidance of Mats Hillert and John Ågren. He then spent ten years as a researcher at the ETH Zürich, Switzerland where he did thermodynamic modelling of BiSrCaCuO high-temperature superconductors and ZrO2–LaMnO3 based solid oxide fuel cell materials with Ludwig Gauckler. Currently he is at the RWTH Aachen University, Germany, first at Materials Chemistry (Jochen Schneider) and since 2013 at the Institute for Materials Applications in Mechanical Engineering (Christoph Broeckmann). Here he has worked on a wide range of materials, mostly metallic, particularly steels, including high-Mn steels, and, more recently, multi-principal element alloys. In all of this work the main focus was on Calphad modelling, developing Calphad databases and their use.
