High-Throughput Nanomechanics and Data-Driven Workflows for Mapping Composition-Microstructure-Property Landscapes — •Ruth Schwaiger — Forschungszentrum Juelich, Institute of Energy Materials and Devices, IMD-1: Structure and Function of Materials, Juelich, Germany

Combinatorial and high-throughput (CHT) methods are enabling nanoscale mechanical studies that span broad compositional and microstructural spaces with unprecedented efficiency. This talk presents an integrated perspective on how automated nanoindentation, combinatorial thin-film libraries, and machine-learning analysis jointly accelerate the discovery of composition-microstructure-property relationships.

Combinatorial thin-film libraries provide dense, continuous coverage across multicomponent compositions, enabling systematic mapping of phase formation, defect structures, and mechanical response. For example, CHT workflows applied to Ni-Al coatings captured structural transitions and hardness trends across the phase diagram, enabling development of a mechanistic hardness model that integrates grain-size, solid-solution, and phase-fraction strengthening. To extract intrinsic material properties from such heterogeneous datasets, data-driven analysis methods, ranging from physics-informed regression to unsupervised clustering, allow the identification of mechanically distinct regions, quantification of data sufficiency, and robust separation of compositional, microstructural, and defect-driven effects.
