The mechanical properties of commercial-purity copper strips subjected to alternating elastoplastic deformation in a mangle have been studied. One pass is shown to be sufficient to increase the yield strength of a treated strip by four times with only a slight change in the ultimate strength and a relatively insignificant decrease in the ductility. The study of the correlation of the hardness with the strength characteristics shows that Vickers microhardness HV0.1 of the treated strip surface increases to a lesser degree than the yield strength does. In this case, the yield-strength Brinell hardness that corresponds to a residual strain of 0.2% increases by almost four times. The strain-hardening coefficients that enter in the Meyer equation for indentation and the Ludwik–Hollomon equation for tension have been determined. Their correlation is observed for the copper strips before and after treatment.
