THE EFFECT OF COLD DEFORMATION ON ELASTICITY AND PLASTICITY OF DRAWN AND ENAMELED COPPER WIRES

The effect of the cold deformation degree during drawing on the shear modulus, spiral elongation, elastic spring back, breaking elongation a nd texture of copper win before and after enameling have been studied. The cause of the wire properties change during an increase of cold de formation degree is a texture change. A method of spiral elongation, w hich is used to estimate the recrystallization ability of copper inten ded to produce enameled wire, can also be applied for estimating the i nfluence of some technological parameters of drawing on the properties of enameled wire.
