Potential of the machining of gamma-TiAl alloys

The provision of new structural materials for heavy duty components for tom orrows aircraft engines is the target of current development of Titanium-Al uminides. Looking towards the acceptance and application of that heat resis ting light weight material the cutting properties using modern edge tools h ave decisive influence. This article describes cutting procedures as used t o machine half-finished products of gamma-TiAl primary cast. Especially the potential and the limitation of the methods to machine this material are d iscussed.
