Meeting 10th International Symposium on Superalloy 718 and Derivatives (2023)
Symposium Superalloy 718 and Derivatives
Presentation Title Meeting the Challenges of the Future by Understanding Our Past
Author(s) Melissa E. Martinez
On-Site Speaker (Planned) Melissa E. Martinez
Abstract Scope 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.
