Intermetallic β‐Solidifying γ‐TiAl Based Alloys − From Fundamental Research to Application

Abstract

Intermetallic titanium aluminides based on the ordered γ‐TiAl phase have gained increasing interest as innovative high‐temperature light‐weight structural materials. They have found application in aerospace and automotive industries and are still subject of worldwide research and development activities. Their attractive properties perfectly match the engine manufacturers’ demands. This review, bridges the gap from the development of the TNM alloy through structural characterization with sophisticated in and ex situ methods, engineering properties, manufacturing, and processing technologies to all aspects of application. Because one thing is clear, the material still has great potential.
