Scope Nickel-base superalloys possess excellent creep strength, oxidation resistance and fracture toughness. This impressive combination of properties makes them the material of choice for many demanding operating environments. Turbine engine propulsion, power generation and many other systems rely on the performance and durability of these high temperature materials to achieve the desired operating efficiency and costs of ownership. As these applications continue to evolve, they demand structural materials that can withstand even higher operating temperatures while at the same time maintaining stability, environmental resistance and mechanical properties. Materials systems that can withstand extreme environments and be fabricated into both rotating and stationary components are critical to the success of future propulsion and power generation systems.

The goal of this symposium is to review recent advancements in materials systems intended to replace conventional superalloy systems in next generation high temperature applications. Materials focus areas include: (1) next generation superalloys, (2) refractory metal-based alloys, (3) intermetallic materials, (4) ceramic-based systems (e.g. SiC-SiC CMCs, oxide matrix systems, etc.), and (5) next generation coatings for the above systems. Topics of interest include, but are not limited to, mechanical (e.g. fatigue, creep), environmental (e.g. oxidation, hot corrosion) and physical properties, as well as long term stability and manufacturing capability.
