The design of new engineering alloys is relying more and more on the aid of computational design and modeling tools. The successful implementation of Integrated Computational Materials Engineering (ICME) is predicated on the accurate knowledge of materials behavior and the links between materials processing, structure, and properties. Experimental investigation is of paramount importance for the calibration and validation of effective ICME tools. This projects looks to bridge the gap between experiment and modeling, experimentally investigating materials behavior in emerging engineering alloys and applications, and using that information to build databases and computational modeling tools to enable more efficient design of next generation advanced materials. Examples of current areas of interest are thermodynamics and phase transformations in high temperature cobalt-based superalloys and microstructural evolution in additively manufactured materials.
