Nanoindentation as a high throughput, screening tool to probe decomposition in HEAs Qualitative characterization of phase formation by Young's modulus analysis Reduction in experimental preparation time compared to advanced microstructural characterization techniques (TEM, APT) Increased strain-rate sensitivity in UFG but also in CG state Strong scatter in Young's modulus in CG and SX state due to elastic anisotropy
