| The silver covered copper composite ingot prepared by the solid/liquid casting method, and after drawing processing, through the annealing to adjustment the performance, prepared the silver covered copper composite fine wire with good mechanical properties. Study the influence law of drawing and annealing process and the technological parameters on the microstructure and mechanical properties of silver covered copper composite. The results show that with the increase of the deformation, the ultimate tensile strength of Ag/Cu composite fine wire is increasing, while the elongation decreases with increasing the deformation. After annealing the most of work hardening in material is eliminating, the plastic improved, the strength declined and elongation increased. |
