N2 - Microstructure evolution, gas content, and properties of the heavily cold-drawn Cu75Cr25 alloy were studied. Results showed that the oxygen and nitrogen contents of Cu75Cr25 alloy prepared by vacuum induction melting in calcia crucibles were low, about 320 and 20 ppm, respectively. The Cu75Cr25 material with low gas content can be cold drawn to lines with diameter less than 0.1 mm, in which Cr phase displays thin and curving morphology. The coherent interface, forming between Cu(111) and Cr(110) during the heavily cold-drawing process, constrained Cr phase and greatly improved its deformability as well as increased the strength of the Cu-Cr alloy. The breaking strength and electrical conductivity of the Cu75Cr25 alloy were about 577 MPa and 60 pct IACS, respectively.
