"Design Approaches for Advanced High Temperature Structural Materials"
In many cases, transformational design concepts are often limited by the capabilities of existing engineering materials. This necessitates the need for the development of advanced materials that can serve as enabling technologies that can be used to realize these concepts. For example, the performance, efficiency and emissions of advanced gas turbine engines for power generation and aerospace propulsion is limited by the temperature capability of the structural materials used in the hot section of the engine. In order to meet future requirements for clean power generation and aerospace transportation, innovative materials and processing approaches are required. Recent advances in these critical technologies can largely be attributed to the development of physics-based computational models and novel characterization tools that provide an improved fundamental understanding of the intrinsic mechanisms governing their characteristic behavior. This talk will discuss some of the advances, challenges and lessons learned associated with developing engineering solutions to overcome these intrinsic limitations and extend the temperature capability of high performance materials used in gas turbine applications.
