This work is focused on the effect of rolling with cyclic movement of rolls (RCMR) on microstructure, mechanical properties and electrical conductivity of CuCr0.6 and CuFe2 alloys in states after applying different heat treatments. The mechanical properties were determined by using MST QTest/10 machine equipped with digital image correlation (DIC). Scanning transmission electron microscopy (STEM) was used for microstructural characterization. The RCMR processed alloys shows high mechanical strength (UTS:539 MPa for CuCr0.6 alloy and UTS:393 MPa for CuFe2 alloy) attributed to the high density of coherent precipitates (after aging at 500 °C/2 h) and ultrafine grained structure. Plastically properties as uniform elongation (Agt) was about (∼1%) for both alloys after RCMR deformation. The RCMR processing induces a significant reduction of the electrical conductivity for samples, which were quenched before deformation, but for samples which were subjected to aging before deformation, the electrical conductivity was restored thanks to precipitation process.
