Development of Microstructure and Micromechanism-Sensitive Property Models and Their Integration into the Design of Advanced Disk and Blade Turbine Systems
Collaborators: M. Mills, Ohio State University
Materials: Metals
Application: Structural
Technique: Processing Characterization

This research program is in collaboration with Ohio State University and Johns Hopkins University. The goal of the program is to develop improved models that will (a) incorporate more realistic representation of the relevant microstructures and micromechanisms, (b) enable modeling for a range of relevant service conditions, (c) address time-dependent deformation in both disk and blade alloys, (d) investigate crack initiation in blade materials, and (d) provide this information even more accessibly to the component design process, building upon the paths to the design process created in the DARPA Accelerated Insertion of Materials (AIM) program. We will be studying the next generation Ni base disk alloy (called ME16 by P&W and R104 by GEAE) and turbine blade alloy (called MX4 by GEAE and PW1497 by P&W) with the goal of providing models that will enable the designer to extend the operating regime with confidence. Both of these alloys are of keen, common interest to our industrial collaborators, GEAE and P&W, for both military and commercial propulsion systems.
