摘要

高强度、高导电率的铜合金需要优异的机械和电气性能。在铜银合金中实现强度-电导率平衡和强度-电导率平衡是一项挑战。在这项研究中，通过冷轧加工出了完全纳米晶的铜-2.9%银-0.6%锆合金。在不同温度下进行老化，以调节微观结构和性能。通过低温时效可以获得优异的机械和电气性能。讨论了优化强度、延展性和导电性的机制。

Optimizing mechanical and electrical properties of a nanostructured Cu-Ag alloy by aging at low temperatures

Superior mechanical and electrical properties are desired in high-strength high-conductivity Cu alloys. It is challenging to achieve strength-ductility balance and strength-conductivity balance in Cu-Ag alloys. In this work, fully nanocrystalline Cu-2.9%Ag-0.6%Zr alloy was processed by cold rolling. Aging at different temperatures was conducted to modulate the microstructures and properties. Superior mechanical and electrical properties can be achieved by aging at low temperatures. Mechanisms for optimizing the strength, ductility and electrical conductivity were discussed.

期刊介绍： Materials Science and Engineering A provides an international medium for the publication of theoretical and experimental studies related to the load-bearing capacity of materials as influenced by their basic properties, processing history, microstructure and operating environment. Appropriate submissions to Materials Science and Engineering A should include scientific and/or engineering factors which affect the microstructure - strength relationships of materials and report the changes to mechanical behavior.
