Abstract Scope |
Superalloys are critical structural materials that ideally suited for high performance gas turbine applications due their excellent resistance to deformation and environmental degradation at elevated temperatures. Although many of the intrinsic characteristics of superalloys can be attributed to the underlying alloy chemistry, in many instances the properties of these alloys can be enhanced through mesoscale engineering or control of the grain boundary character and morphology. The emergence and acceptance of ICME design methodologies within the materials community has contributed greatly to the fundamental understanding of how microstructure evolves during thermal-mechanical processing. This talk will describe how we have applied this knowledge to develop innovative thermal-mechanical processes that can be effectively utilized to engineer the grain boundary character and morphology of Ni-base superalloys and enhance the creep and dwell fatigue performance of the material. |
