- Aeroengine shafts are made currently by joining a tough steel to a creep-resistant steel. We have developed a new steel that serves both purposes, is much stronger, and provides a single-shaft solution for future aeroengine programmes. The steel is now at an advanced level of technology readiness with component-level testing in progress (Rolls Royce Technical Specialist Materials Engineer, contact details available). The now patented concept (GB1016731.0 and US 9217186) relies on a complex precipitation-hardening scenario that includes fine intermetallic compounds and some specific additions to control the grain structure.
