The effects of thermo-mechanical processing and a trace amount of carbon addition vere studied on tensile behavior of Cu-2.5Fe-0.1P alloys. In this study, Cu-2.5Fe-0.1P alloy sheets without and vith a carbon content of 0.05 wt% were cast and subsequently rolled and thermo-mechanically treated folloingvarious processing mute. The introduction of intermediate aging treatment between cold rolling improved the tensile strength Solutionheattieatrnentpriorto aging was proved to be detrimental on the tensile strength The effect of C addition on improving the strength was real but marginal, probably due to the limited solubility of C in Cu-2.5Fe matrix. The effect of intennediate aging on tensile strength of Cu-2.5Fe-0.1P specimens vith and vithout C addition are discussed based onTEMmicrographs and SEM fractographs.
