The precipitation hardening of binary Fe-Cu alloys by thermal aging at 550°C was investigated by using Small Angle Neutron Scattering (SANS), Vickers hardness (HV 10) and micromagnetic measurements. SANS and Vickers hardness measurements showed that the amount in Cu precipitates increases with rising Cu content. The micromagnetic measurands show a dependence on the Cu content. The results derived from the investigation of Fe-Cu samples agree with those obtained from investigation of WB 36 steel. Additionally, the influence of plastic deformation on micromagnetic measurands was studied.
