This project aims to investigate the combined mechanical responses of 3D nano-architected oxides under the influence of electron-beam irradiation, strain rate, and temperature. The intrinsic brittleness of oxides can be alleviated through variations in temperature, material size, and the application of electron-beam irradiation [1,2]. In this study, the combined effects on the mechanical response of 3D nano-architected oxides will be systematically examined using an in-situ SEM micromechanical testing system equipped with a piezo-actuator and precise temperature control systems. This project seeks to deepen the understanding of oxide deformation induced by electron-beam irradiation and its dependencies on size, strain rate, and temperature. more

Alloying elements tend to accumulate in grain boundaries either as atomic segregants or precipitates. The group partners aim to distinguish between the segregation and precipitation impact on local physical properties of the boundaries. more

The research group explores innovative research on the material – light elements interactions, a research field with relevance for nuclear and fusion reactors, as well as for materials required for the hydrogen economy. The major aspects of research are studies on sinks for He and H in metals (e.g., precipitates, interfaces, grain boundaries), and their evolution at elevated temperature. Based on this knowledge, we aim to establish He and H tolerant refractory materials via microstructure tailoring and optimization. more

Additive manufacturing via selected laser melting (SLM) is a promising fabrication technique that can enable unique alloy design pathways due to rapid heating and solidification. This group aims to exploit such process characteristics of SLM to achieve refined micro and nanostructures that will in turn enhance the mechanical and physical performance of complex 3D architectures in both static and dynamic loading conditions. more

High temperature materials are used for critical components in gas turbines for power plants and aero engines, chemical/metallurgical plants and motors for ships and cars. more

Future technology challenges will no longer be simply addressed by today's materials and processing solutions, which are often based on trial and error. Instead, guidance will be attained from correlative experimental and theoretical research bridging all length scales.
