Two are the guiding objectives of the M4F project:

To develop physical understanding and predictive models of the origin of localised deformation under irradiation in F/M steels and its consequences on the mechanical behaviour of components for future fission and fusion reactors, in order to enable their design based on robust standards.
To develop best practice methodologies to use ion irradiation as a tool to evaluate radiation effects on materials, applied to F/M steels: not only microstructural changes, but also mechanical property changes, via nanoindentation, which is a suitable technique to test the limited thickness affected by ion irradiation.
