New methods and opportunities across the scales - On complex crystals, lattice defects and deformation damage
At IMM in Aachen we aim achieve new insights into the physical mechanisms of deformation of intermetallic and metallic materials (and their composites). We do this across the scales from the crystal structure of intermetallics to the formation of µm-sized pores and cracks in steels during forming. In this presentation, I will therefore provide an introduction to three topics: (1) the search for new descriptors of plasticity in complex intermetallic crystals, with the aim to provide us with better guidance to identify promising hard, but also sufficiently tough, phases; (2) our recent efforts to join the concepts of defect engineering and phase stability in order to develop a new framework considering defects, like dislocations or grain boundaries, in terms of their atomic structure and chemistry which at the same time also gives them a thermodynamic stability; and (3) the use of machine learning to analyse damage mechanisms in dual phase microstructures, where heterogeneity from the micro-scale of individual phases to the macro-scale of banded sheets requires a combination of both high resolution and large area observation in electron microscopy – and us to re-evaluate how rigorously we analyse and interpret our data normally.

Prof. Sandra Korte-Kerzel is head of the Institute of Physical Metallurgy and Materials Physics (IMM) and holds the Chair of Materials Physics at RWTH Aachen University. After her studies in Aachen, Christchurch (NZ) and Cambridge (UK), she was Junior Professor of Micromechanics of Materials at FAU Erlangen-Nürnberg before coming to Aachen in 2013. She is spokesperson of the Collaborative Research Centre SFB 1394 ‘Structural and Chemical Atomic Complexity – From Defect Phase Diagrams to Material Properties’ and was awarded an ERC Starting Grant in 2019 on ‘Fundamental Building Blocks –Understanding plasticity in complex crystals based on their simplest, intergrown units’ (FunBlocks).
