MEANS 2: Microstructure-and Micromechanism-Sensitive Property Models for Advanced Turbine Disk and Blade Systems

Abstract

The overall coordinated research effort involved activities in the following areas: (1) Creep and Deformation Structure Characterization Studies of Disk Alloy Rene 104 (ME3), (2) Calculation of Activation Barriers Using Phase Field Dislocation Dynamics, (3) Adaptive computational model of crystal plasticity involving micro-twinning, (4) 3D Atom Probe Analysis of Phase Microstructures. Descriptions of all activities can be found in the annual and final reports submitted and to be submitted by the overall PI, Mike Mills.
