摘要

In the present study,Cu-modified pipeline steels were fabricated to mitigate MIC by the antimicrobial ability of Cu element.The microstructure,mechanical properties and the antimircobial performance of the Cu-modified steel were systematically investigated.The Cu-modified steels showed good antimicrobial performance with remarkable strength enhancement by nanoscale Cu-rich precipitates and good impact toughness without changing the original base microstructures after the optimal aging treatment of 500 ℃/1 h.
