摘要：

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 degrees 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.
