Meeting the Challenges of the Future by Understanding Our Past: Melissa Martinez1; 1ATI Metals
Spanish Philosopher George Santayana wrote in The Life of Reason, “Those who cannot remember the past are condemned to repeat it". This presentation is intended to cover portions of ATI’s history related to alloy 718 and its derivatives. Company heritage and the key melting, thermomechanical processing and modeling processes will be covered. The presentation will conclude by touching on the continued advances being fueled by the growth of accessible data, characterization tools, process controls, recipe systems and the potential of machine learning.
7:35 PM Keynote
Application of Computational Materials and Process Modeling to Current and Future Aero-engine Component Development and Validation: David Furrer1; 1Pratt & Whitney
Computational materials and process modeling capabilities have evolved over the past several decades. More recently, the Materials Genome Initiative (MGI) has provided focus on this technology and its application for rapid and lower cost materials and process development and implementation. Integrated Computational Materials Engineering (ICME) is now part of many organizations’ engineering and design approaches and associated infrastructures. Nearly all current new and future materials and process technology developments do or will involve application of modeling and simulation. The evolution of materials modeling and application to mainstream and emerging supply-chain processes will be reviewed with some perspectives on what the future might hold. Special emphasis will be made to review application of ICME Alloy 718 and derivative materials and components. The use of computational modeling and simulation to material and process development is being extended to component qualification and certification. There are significant opportunities and prospects for materials and process modeling to enable further advancements in alloy design and definition, materials processing methods development, and enablement of enhanced utilization of material capabilities to new product application spaces.
