摘要：

We fabricated ultrafine-grained (UFG) Cu-Cr-Zr alloy including fine second-phase particles via an accumulative roll-bonding process and subsequent aging treatment. The nanosized precipitates dispersed within the UFG matrix significantly enhanced strain hardening, resulting in the simultaneous improvement of uniform elongation and tensile strength.
