  Samples consisting of one ferromagnetic and one diamagnetic component which
are immiscible at the thermodynamic equilibrium (Co-Cu, Fe-Cu, Fe-Ag) are
processed by high-pressure torsion at various compositions. The received
microstructures are investigated by electron microscopy and synchrotron X-ray
diffraction, showing a microstructural saturation. Results gained from
microstructural investigations are correlated to magnetometry data. The Co-Cu
samples show mainly ferromagnetic behavior and a decrease in coercivity with
increasing Co-content. The saturation microstructure of Fe-Cu samples is found
to be dual phase. Results of magnetic measurements also revealed the occurrence
of two different magnetic phases in this system. For Fe-Ag, the microstructural
and magnetic results indicate that no intermixing between the elemental phases
takes place.
