Study of high-strength and high-conductivity Cu–Sn–Fe alloys

Abstract

Cu-Sn-Fe alloys with different compositions were developed by casting, normalizing treatment, cold roll and subsequent annealing treatment. The results showed that the tensile strength and resistivity of the Cu-xSn-xFe alloys (where x represents wt.%) improved with increasing the content of Sn and Fe. Compared with the as-cast alloys, the resistivity and tensile strength of the Cu-xSn-xFe alloys after normalizing and cold rolling treatment increased. In addition, the resistivity and mechanical properties of the alloys after the annealing treatment were improved significantly. Finally, a conclusion could be drawn that the annealed Cu-2Sn-5Fe alloy had good mechanical properties and resistivity, and the values of the tensile strength, mechanical elongation and resistivity reached 552 MPa, 32 % and 1.92 µΩ·cm, respectively.

Characteristics and Abrasive Wear Resistance of Plasma Alloyed Layers Based on Tin Bronze and Chromium Carbide

“…Currently, in order to improve the properties of materials, not pure copper is introduced into the iron base, but alloys based on it, such as bronze powder. The combination of Fe, Cu and Sn has been shown in the creation of composite alloys of the Fe-Cu-Sn system [14][15][16][17]. Iron, copper, and tin composites are used in various tribological applications due to their high hardness, high strength, and moderate wear resistance [16,17].…”

It was noted in [17] that the ultimate strength and resistivity of Cu-Sn-Fe alloys increase with increasing Sn and Fe content. In determining the cohesive energy between atoms in a metal-to-metal transition layer using traditional (Fe-Sn) and proposed (Fe-Cu-Sn) technologies, it was proved that copper should be used to increase the bonding strength of the babbitt layer to the steel substrate.…”

Recrystallization behaviour during annealing of cold-rolled Cu–5Fe–2Sn alloy

“…Owing to the low preparation cost and abundant raw materials, Cu-Fe alloy has been widely concerned and extensively explored [9][10][11][12][13][14]. J. T. Zhang et al [15] found that the solidification microstructure of the high strength and high conductivity Cu-Fe-Sn alloy prepared by use of copper mould rapid cooling method can be refined. After cold deformation to a certain extent and annealing at a certain temperature, the comprehensive properties of the alloy can be improved.…”
