摘要：

Design: concept of dual-phase copper alloys was attractive to improve the mechanical performance of Cu. However, a systematic understanding of the interactions between second phase, twins, and dislocations in dualphase copper alloys during deformation was urgent for further strengthening their mechanical properties. Herein, models of dual-phase Cu-Fe alloys with different Fe contents were established and simulated to deeply investigate the interaction between Cu matrix and Fe-enriched phase during deformation as well as the dislocation proliferation and structural changes at the atomic scale. ...
