- •
Improvement of conventional 9%Cr RAFM steels by thermo-mechanical treatments has been demonstrated.
- •
Superior strength and prolonged creep lifetime has been found for EUROFER steel after TMT (e.g. 50 MPa in tensile strength at high temperatures).
- •
A nano-scale precipitation of strengthening secondary phases was found inside the materials.
