Experimental techniques for rapid collections of materials data and holistic approaches to integrate experimental and computational data will be described with examples. Localized property measurements on composition gradients created in diffusion multiples allow high-throughput collection of several materials properties as a function of composition, in addition to phase diagrams and diffusion coefficients.
A novel approach was developed to rapidly establish reliable diffusion coefficient (atomic mobility) databases by holistically integrating both experimental and computed data. Dual-anneal diffusion multiples allow rapid and systematic collection of big datasets of phase precipitation kinetics and morphological evolution across wide ranges of compositions as a function of time and temperature. An approach that iteratively and holistically integrate experimental results with model predictions can be the most effective in both establishing materials databases and understanding of various mechanisms.
