Abstract
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.
