PhD student for analysis of phase transformations in metallic solid glasses at the atomic level

ETH Zürich • Zürich • vor 2M

ETH Zurich is one of the world's leading universities that specialize in science and technology. It is renowned for its excellent education, its cutting-edge fundamental research and its efforts to put new knowledge and innovations directly into practice. The Laboratory of Metal Physics and Technology (LMPT), part of the Department of Materials at ETH Zurich, conducts research and teaching in areas ranging from basic science to technology, mostly in metal-related areas. It is led by Jörg F. Löffler and brings together leading physicists, materials scientists, chemists, and biomedical engineers from across the world. LMPT creates novel materials and explores emerging phenomena in metal physics and technology via detailed materials analysis and modeling.

Project background

Are you ready to dive into Materials Science?
We are looking for a PhD candidate at the Laboratory of Metal Physics and Technology (LMPT) to investigate the atomic-scale processes underlying phase transformations in bulk metallic glasses (BMG), with a focus on the interplay between atomic arrangement, dynamic heterogeneities, medium-range order (MRO), and nucleation and crystallization phenomena. Bulk metallic glasses are a unique class of materials with exceptional mechanical and physical properties, making them highly attractive for advanced engineering applications ranging from biomedical devices to aerospace components. Despite their promise, the fundamental mechanisms governing their (metastable) phase transformations remain incompletely understood, especially under varying external stimuli.

Project Overview

The successful candidate will utilize advanced analytical and high-resolution transmission electron microscopy (TEM)-including potential collaborations at the Jülich Research Center-to directly observe structural changes at the atomic level. Fast scanning calorimetry and synchrotron radiation techniques will be employed to probe the kinetics and thermodynamics of phase transformations. The project will explore how temperature, mechanical strain, and irradiation induce changes in atomic structure and dynamics. The influence of atomic arrangement on stability, transformation kinetics, and crystallization will be systematically investigated.
