Introduction Titanium technology development for aero-engines has been driven by the design engineers' constant desire to gain increasing performance at reduced weight.
The philosophy behind IMI834 was to have a highly alpha strengthened near alpha alloy but to engineer the alloy composition to give a sufficiently wide heat treatment window to reproducibly produce ~5% of retained alpha phase in a transformed beta structure.
The first civil engine applications are likely to be static parts such an engine thrust strut or the supporting struts that form part of the engine mounting structure.
Within the next 10 years introduction of high temperature intermetallic composites should be possible and the emergence of nano-engineered titanium materials and composites could be seen.
