Book Description
Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, with significant weight-savings while maintaining comparable mechanical properties. New gamma titanium aluminide alloys and an appropriate fiber could offer an improved TMC for use in intermediate temperature applications (400-800 C). The purpose of this investigation is the evaluation of a gamma titanium aluminide alloy with nominal composition Ti-46.5Al-4(Cr, Nb, Ta, B)at.% as a structural material in future aerospace transportation systems, where very light-weight structures are necessary to meet the goals of advanced aerospace programs.Johnson, W.

Book Description
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

Book Description
Gamma Titanium aluminide sheet structure technologies are focused on in this effort, including experiments to evaluate laser beam welding of thin sheet structure; superplastic forming and diffusion bonding of thin sheet structure; and, demonstration of fabricability of a hot-formed "egg crate" type core with brazed top and bottom face sheets. The fabricated subelement is known as "gator hide" and has the potential to replace more conventional honeycomb structure. All three area demonstrations were successful.

Book Description
The International Symposium "Fatigue under Thermal and Mechanical Loading", held at Petten (The Netherlands) on May 22-24, 1995, was jointly organized by the Institute for Advanced Materials of The Joint Research Centre, E. C. , and by the Societe Fran~se de Metallurgie et de Materiaux. The fast heating and cooling cycles experienced by many high temperature components cause thermally induced stresses, which often operate in combination with mechanical loads. The resulting thermal / mechanical fatigue cycle leads to material degradation mechanisms and failure modes typical of service cycles. The growing awareness that the synergism between the combined thermal and mechanical loads can not be reproduced by means of isothermal tests, has resulted in an increasing interest in thermal and thermo-mechanical fatigue testing. This trend has been reinforced by the constant pull by industry for more performant, yet safer high temperature systems, pushing the materials to the limit of their properties. Dedicated ASTM meetings in particular have set the scene for this area of research. The proceedings of the symposium organized by D. A. Spera and D. F. Mowbray in 1975 provided a reference book on thermal fatigue which reflects the knowledge and experimental capabilities of the mid-seventies.
