Abstract
QuesTek Innovations will employ a computational materials design approach to high-temperature aluminum alloys, addressing glass-forming alloys compositions that can be fully devitrified to desired novel dispersions of stable, low-misfit, coherent,multicomponent L12-structured A13X compounds with coarsening resistance to 300 oC. Building on the research of its Phase I SBIR, QuesTek will undertake model and database development including thermodynamics, mobilities, liquid viscosity and molarvolumes, while constructing a theory of nucleation incubation in multicomponent systems, for incorporation in a new numerical precipitation model to be applied to both glass formation and devitrification dynamics. Electronic - level calculations will helpidentify desirable alloy components for both phase stability and misfit control. Atom-probe microanalysis of glass devitrification in design prototypes will quantify essential diffusion and decomposition behavior.
