High Temperature Alloys

	Cobalt Alloys Pete Bocchini and Daniel Sauza We are developing new high temperature alloys based on the Co-Al-W ternary system. The micro- and nanostructures of these alloys are investigated using SEM/EDS and Atom Probe Tomography; creep and hardness tests are conducted to determine mechanical behavior at ambient and elevated temperatures.
	Iron Alloys Mike Rawlings and *Dr. Nhon Q Vo We are investigating how the processing/microstructure relates to the creep resistance of Fe-Al-Cr-Ni-Ti based alloys that are strengthened by a hierarchical precipitate structure. This link is observed both experimentally and computationally. (Image by Professor Ghosh)
	Aluminum Alloys Philipp Okle, Dr. Nhon Q Vo and Tianyu (Judy) Zhu We investigate microstructure and creep properties of binary and ternary Al-Sc-X, Al-Ti-X and Al-Zr-X alloys with nanoscale, coherent, coarsening-resistant precipitates.
	Nickel alloys Dr. Dinc Erdeniz, Dr. Cong Wang and Ashley Paz y Puente We are developing Ni-based superalloys with topologically-optimized micro-architectural features. We use the pack cementation technique to add Al,Ti and Mo to woven or braided structures fabricated from Ni or Ni-Cr wires and transform them into creep- and oxidation-resistant superalloys.
