Research Interests

Haydn Wadley’s research interests are very broad and span the synthesis, structure and performance of novel materials. Current areas of interest include multifunctional cellular materials for thermal management (e.g. the leading edges of hypersonic vehicles), adaptive/deployable structures, ultralight materials/structures and crushable structures for localized impulse mitigation. He also anticipates several research openings for graduate students in the thermal barrier coatings arena where novel rare earth zirconate/refractory metal multilayers are being investigated. Professor Wadley is a University Professor and the Edgar Starke Research Professor of Materials Science and Engineering. He leads a multi-disciplinary research group that studies the synthesis and processing of materials and the relationships between composition, structure, and properties. He has developed several directed vapor deposition processes and uses them to make multilayer thermal barrier coatings and thin film lithium ion battery systems. His group characterizes the structure of these materials and their key performance defining properties and then explores how to optimize performance by control of the processing environment. Modeling plays a key role in this optimization. His modeling research in this area has spanned vapor transport and atomic/molecular assembly using kinetic Monte Carlo, molecular dynamics and density functional methods.

Dr. Wadley's research group also explores the design and fabrication of synthetic cellular materials and investigates their use for thermal management and impulse load mitigation. He develops novel fabrication approaches that enable the topology and cell wall materials to be varied to maximize performance. For some applications, heat pipe principles have been integrated with cellular structures resulting in thermal management systems with exceptional thermal transport and dissipation performance.

His groups' past sensor research has addressed many aspects of the interaction of elastic and electromagnetic fields with materials and led to the development of numerous in-situ process control sensors. These sensors have been applied to control processes ranging from the growth of II-VI semiconductor crystals to the continuous casting of steel. The integration of advanced sensors, process models and feedback control concepts has become known as intelligent materials processing of materials (IPM) and his IPM laboratory uses this approach for making the novel materials described above. His research group has been awarded (or has pending) many patents. They have developed several processing technologies that are being commercialized. They include two vapor deposition technologies (directed vapor deposition and energy modulated vapor deposition) and several processes for making cellular materials with lattice truss topologies from a wide range of engineering materials including light metals, superalloys, and high performance composites.
