Abstract

The work aims to fabricate a copper-iron alloy with high iron content and to ensure that it has good strength and plasticity while still maintaining its excellent electrical conductivity to meet the demand for high-performance materials in industrial production. Copper-iron alloy single-arm walls with a length, width and height of 200 mm×8 mm×36 mm were prepared by plasma deposition technique, after which the materials were hot rolled at 900 ℃ with a rolling volume of 70%. The microstructure and physical phase of the copper-iron alloy in the deposited and hot-rolled states were observed by electron microscope and X-ray diffractometer, and the mechanical properties and electrical conductivity changes of the copper-iron alloy in the deposited and hot-rolled states were analyzed. After hot rolling, the Fe phase particles inside the alloy were changed from 5-10 μm spherical or oval grains to 30-50 μm dendritic crystals, which were oriented and arranged along the rolling direction, and defects such as pores inside the alloy in the sedimentary state were eliminated. The density of the Fe phase in the alloy decreased because hot rolling caused the Fe phase particles in the alloy to fuse and increase in size. In terms of properties, compared with the alloy in the deposited state, the average hardness of the alloy in the rolled state was increased by 30% to 140HV0.5; the tensile strength was increased by 120% to 434 MPa; the elongation was increased to 24.7% and the electrical conductivity was increased to 89.8% IACS. Plasma deposition combined with the hot rolling process fabricates high Fe-containing CuFe alloys with a certain degree of strength and plasticity and good electrical conductivity, and provides a new method for industrial production.
