This book is a collection of papers presented at the 4th International Symposium on Gamma TiAl Alloys (ISGTA 2014) that was held in conjunction with the 2014 Annual Meeting of The Minerals, Metals & Materials Society. Papers discuss and assess advances in application and implementation experience in current alloys, fundamental
aspects in current gamma alloy materials technology, new processes development and assessment, and emerging new alloys, their potentials and limitations, and breakthroughs.
Papers that originated in the panel discussion of the symposium are intended to help the scientific community realize the limitations of current alloys materials and processes and discuss possible solutions. Six topic areas selected for this purpose included:
- Wrought-processed alloys: status, dilemmas and pathways to future
- Cast alloys for aero engine applications: status, issues, and barriers to advances
- Cast alloys for turbocharger wheels: status and barriers to widespread applications
- Emerging new alloys: justification, potentials, status, and future
- Novel processes: justification, potential vs. realization issues, and future
- Future applications and realistic pathways to them
