General areas of research include integrated computational materials engineering (ICME) including development of integrated multi-scale approaches to design of high performance metal alloys. This work involves the development of advanced materials characterization techniques such as electrostatic levitation (ESL). This technique has been utilized in the characterization of thermophysical and thermochemical properties of high temperature metal alloys in solid and liquid phases. Additionally, the microstructural evolution of alloys as a function of cooling rates is being investigated. Our work includes the experimental validation and integration of simulation methods including calculation of phase diagram (CALPHAD) analysis, classical molecular dynamics, phase field models, and continuum mechanics. This work has been conducted in support of design and optimization of materials and processes with applications in advanced manufacturing (laser based additive manufacturing), aerospace, biomedical, and energy systems. Characterization and simulation of as-built additively built materials include nickel based superalloys for aerospace applications as well as aluminum based alloys in support of in-space manufacturing.
