Abstract

The age-hardening phenomena in 0.3%Zr-Cu base ternary alloys have been studied in order to improve the mechanical properties of Cu-Zr alloy. As the third elements, Fe,Ni,Co,Cr,Si,Al and Be were selected. The results obtained have been summarized in the following: The aging effects on hardness and tensile strength of these alloys are more remarkable than that of Cu-Zr alloy. The maximum values of the properties obtained by aging are presented in Fig. 9 as compared those of Cu-Zr alloy. The electrical conductivity and the mechanical properties of Cu-Zr-Cr alloy are improved markedly, so this alloy is very promising as a high-strength copper alloy with good electrical conductivity.
