FORCE Seminar 2025.09.26 Klaus-Dieter Liss Title: Metals under extremes: Characterization, physical behavior and structural design under high pressure and after high-pressure torsion processing Abstract: The development of advanced technologies requires metals and materials that can withstand extreme environments, including ultra-high temperatures, pressures, and radiation damage. Conversely, such extreme conditions can also be exploited to design new materials with unprecedented properties. Central to both aspects is the characterization of materials — particularly their defect structures — under in-situ conditions at high temperature. This talk will present advanced neutron and synchrotron diffraction techniques for probing structural states, their evolution, anisotropy, and inhomogeneity at room temperature and during heating. Following a brief introduction to modern diffraction methods and their complementarity in studying thermo-mechanical processes, an example of in-situ high-pressure and high-temperature experiments on titanium aluminides will be given. The focus will then shift to materials processed by high-pressure torsion, where the mapping reveals inhomogeneities, residual stresses, and textures. Heating experiments further elucidate microstructural evolution, stress relaxation, dislocation density, grain size changes, recovery, recrystallization, and grain growth. Some systems additionally undergo phase transformations, such as the precipitation of secondary phases, which may be accelerated by the high stored energy in the material. Finally, an outlook will be provided on future applications using FORCE equipment — especially the Twister — for the design of next-generation structural and functional materials.

FORCE Seminar 2025.03.28 Rebecca Fischer Title: The light element composition of Earth’s core Abstract: The Earth’s Fe–Ni core is known to contain ~10% “light elements” (e.g., Si, O, S, C, H) whose identities and abundances are controversial. Many different approaches can provide insights into Earth’s core composition, including those based on cosmochemistry/geochemistry, physical properties of the core, and metal–silicate reactions during core formation. In this talk, I will review the available constraints on core composition from high pressure experiments, synthesizing previous results from our group and many others. In particular, I will focus on comparisons between seismic data and high P–T experimental measurements of the densities, sound velocities, and phase relations of Fe-rich alloys, as well as high P–T metal–silicate partitioning experiments and the incorporation of their results into core formation models. While Earth’s exact core composition remains elusive, this type of integrative approach is particularly useful for placing bounds on light element abundances and identifying which types of future high pressure measurements will be the most helpful in constraining the core’s composition.
