논문 초록 (Abstract)
High strength high conductivity Cu-1%Cr-Mg-P alloy was selected as a base composition and Ag was added to the alloy in order to further increase the strength without sacrificing the conductivity. SEM and TEM analyses indicated that very fine MgP and Ag(Mg) precipitates were formed in addition to relatively large Cr phase in the Cu matrix. Significantly high strength could be obtained through the special cold rolling at an extremely low temperature using liquid nitrogen. The electrical conductivity of alloy was slightly decreased by the Ag addition, but the tensile strength could be further enhanced by it.
