Structure/Property Relations, MST-8 
The crystal growth & material preparation teamTeam Leader: Ken McClellan Research GoalsThe goal of the team is to perform experimental, theoretical, and computational work to relate the structure of multi-component materials to their thermodynamic properties and phenomena. To achieve the goal, team members are engaged in synthesis of complex alloys and ceramics, advanced characterization techniques, development of multi-scale models of thermo-mechanical and thermo-chemical properties, and computer simulations of transport phenomena. Properties of InterestThe TKM team studies structure and lattice parameters, heat capacity, enthalpy, entropy, free energy, formation free energy, thermal expansion coefficients, thermal conductivity coefficients, species mobility, bulk modulus, equation of state, free energy of chemical reactions, and chemical reaction constants. Phenomena of InterestOf particular interest are stability of phases, phase transformations, heat transfer (conduction, convection, and radiation), mass transport (diffusion of species), and kinetics of chemical reactions. Growing Single CrystalsPart of the TKM team specializes in a unique area--the ability to grow high-purity "custom" single crystals. This is a critical capability for research on advanced high-temperature, radiation-resistant, detector/sensor, and electronic materials where synthesis of new materials and subsequent doping studies within an identified system are essential. In the Single Crystal Growth Labortory (SCGL), TKM staff work with users both internal and external to the Laboratory to grow research-size rods of single crystals, including refractory metals, intermetallics, and complex oxides and non-oxides.
