Effect of working temperature on young's modulus of electrolytic copper

Abstract

Electrolytic copper wires of different grain diameters were given variable amounts of plastic strain, and then subjected to increased tensile loadings at different working temperatures. The associated changes in Y. M. were measured. Plastic strain decreased Y. M. at first to a minimum value, then it increased Y. M. This effect was interpreted in terms of texture variations and mutual dislocation interactions. Increasing working temperature decreased Y. M. because of accompanying increase in slip distances.
