Abstract On the basis of computer-calculated yield functions, the work hardening of 〈100〉 textured Cu-0.64 at % Co-0.48 at % Si and 〈111〉 textured polycrystalline copper wires were studied by simultaneous torsion and extension and by pure extension. Representing the work hardening by resolved shear stress-resolved shear strain curves, the rate of hardening is significantly lower for torsion than for pure extension. This behaviour is explained by the operation of different slip systems activated in the two modes of deformation. In the 〈100〉 textured Cu-Co-Si wires, heterogeneous plastic deformation was observed beyond about 80% shear strain.
