“…Zhang et al reported that the conductivity of a Cu-30Fe alloy prepared by powder metallurgy and cold rolling was 38% IACS, and the strength was 826 MPa [37]. These, in combination with the previous studies, reveal a simple law: the Cu-Fe alloy with a low Fe content has a high EC but a low UTS, while the Cu-Fe alloy with a high Fe content tends to have a high UTS but a low EC [6,7,18,19,25,32,[37][38][39][40][41][42].…”

To study the effects of Fe content and cold drawing strain on the microstructure and properties, Cu-Fe alloys were prepared via powder metallurgy and hot extrusion. Scanning electron microscopy was applied to observe the Fe phase, and the ultimate tensile strength was investigated using a universal material testing machine. Alloying with an Fe content below 10 wt.% formed a spherically dispersed Fe phase via the conventional nucleation and growth mechanism, whereas a higher Fe content formed a water-droplet-like Fe phase via the spinodal decomposition mechanism in the as-extruded Cu-Fe alloy. Further cold drawing induced the fiber structure of the Fe phase (fiber strengthening), which could not be destroyed by subsequent annealing. As the Fe content increased, the strength increased but the electrical conductivity decreased; as the cold drawing strain increased, both the strength and the electrical conductivity roughly increased, but the elongation roughly decreased. After thermal–mechanical processing, the electrical conductivity and strength of the Cu-40Fe alloy could reach 51% IACS and 1.14 GPa, respectively. This study can provide insight into the design of high-performance Cu-Fe alloys by tailoring the size and morphology of the Fe phase.

“…The precipitates enhance the alloy's stress resistance by preventing the migration and sliding of dislocations. The reinforcement increment of the precipitated nano-Fe phase is consistent with Orowan reinforcement and can be expressed as [34]: where ν represents Poisson's ratio, d precip and f precip represent the diameter and volume fraction of the precipitated Fe phase, respectively, which can be obtained from Figure 7, and the related parameters are shown in Table 2. The precipitation phase strengthening values of the Cu-5Fe and Cu-5Fe-0.15Sn alloys after aging at 400 °C were calculated by Eq.…”

The Cu-5Fe-xSn alloy was prepared, and the effect of Sn on Fe phase distribution, precipitation kinetics, and properties of the Cu-5Fe alloy were investigated. The tensile strength and conductivity of Cu-5Fe-0.15Sn after aging at 400°C were 712 MPa and 66.6% IACS, respectively. Compared to the Cu-5Fe alloy, the tensile strength increased by about 190 MPa, while the conductivity decreased by only 1.4% IACS. Sn optimises Fe distribution and inhibits dendritic segregation. After drawing, the Fe phase is transformed into Fe fibre. Sn enhances the synergistic deformation ability of Cu/Fe, resulting in better continuity and density of Fe fibres. The precipitation activation energies of Fe in Cu-5Fe and Cu-5Fe-0.15Sn alloys were 95.9 and 84.9 kJ/mol, respectively. HIGHLIGHTS The addition of Sn significantly improves the mechanical properties of Cu-5Fe alloy. Sn addition optimised the primary Fe phase distribution and increased the Fe fibre density. The addition of Sn reduces the ultimate solid solubility of Fe in Cu and promotes the nucleation of γ-Fe phase. Sn reduces the activation energy of Fe phase and promotes the precipitation of Fe phase.
