Abstract Scope Titanium alloys and their composites were developed and are evolving for applications in aero-engines as fan blades, compressor discs & blades and other parts at least up to 1073K to reduce weight and fuel consumption. Fine structural changes like the precipitation of silicides and/or Ti3Al or both the phases and other changes in the conventional alloys during service conditions impact properties and there are differences. Further, intermetallic TiAl alloys have been developed and already replaced some heavier nickel base alloys. Various creative cost effective processes are being studied and developed to make these parts with improved microstructures and thus properties. Concepts about more advanced alloys and composites are in the works to push to higher temperature limits. It is attempted to bring out the current state of the understanding of these materials, process technology and possible future trends are presented.
