  1. MEANS2 Microstructure- and Micromechanism-Sensitive Property Models for Advanced Turbine Disk and Blade Systems Objective: Develop physics-based understanding and modeling capability for deformation/damage mechanisms in Ni-base disk and blade alloys Approach: Integrated experiments and modeling for microstructure and micromechanisms developed in collaboration between AFRL, industry partners and universities Payoff: Improved fidelity of AIM property and microstructure evolution models AFOSR Grants: • FA9550-05-1-0135 (OSU) • FA9550-05-1-0100 (UofM) • FA9550-05-1-0102 (JHU) Funding: • AFOSR to OSU $ 1,119K • AFOSR to UofM $ 285K • AFOSR to JHU $ 195K • Total $ 1,599K Duration: Feb 05 - Feb 08 Team Gov’t AFOSR Manager: Brett Conner Gov’t Technical Manager: Dennis Dimiduk OSU Program Manager: Michael Mills UofM Program Manager: Tresa Pollock JHU Program Manager: Kevin Hemker 9 Faculty & 4 AFRL Mentors (+ Students)

  2. MEANS 2: Approach forDevelopingMicrostructure- and Micromechanism-Sensitive Property Models Microstructure Modeling + Calibrating Experiments Micromechanical Modeling + Calibrating Experiments Processing Microstructure Properties Goal: Augment/replace costly and time-intensive empirical databases with microstructure-sensitive, mechanism-based materials models. Slow Cool Fast Cool Transitions: Providing fundamental micro-mechanical insights for the AIM augmentations at Pratt and Whitney and GEAE, and for the DARPA-Prognosis and NASA-Propulsion 21 efforts.
