采用固/液浇注法制备了银包铜复合锭坯，经拉拔加工后，通过退火进行性能调控，制备出力学性能较好的银包铜复合细丝。研究了银包铜复合材料拉拔及退火工艺，以及工艺参数对组织和力学性能的影响规律。结果表明，随着变形量增加，Ag/Cu复合细丝极限抗拉强度是呈增加的趋势，而伸长率是随变形量增大而减小。退火后材料加工中产生的较大加工硬化得以消除，使其塑性提升，主要表现为强度下降、延伸率增大。

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.
