| Abstract Scope |
This talk will highlight recent advances in high-throughput measurements of alloy phase diagrams and phase-based properties. Diffusion multiples offer an efficient means to determine alloy phase diagrams via local equilibrium analysis at phase interfaces. Micron-resolution property measurements on composition gradients created in diffusion multiples allow effective collection of composition-dependent properties such as conductivity and elastic constants. A forward-simulation analysis allows accurate measurement of both impurity (dilute) diffusion and interdiffusion coefficients for the establishment of reliable diffusion (mobility) databases. Dual-anneal diffusion multiples (DADMs) allow rapid collection of large and systematic datasets on phase precipitation kinetics and morphological evolution across wide ranges of compositions as a function of time and temperature. Such datasets will be very valuable to testing and improving models. Examples will be used to illustrate the effectiveness and future essentiality of tight integration of computational and experimental approaches to rapidly establish digital materials property databases for accelerated alloy design. |
