Comparison of Ag and Zr with same atomic ratio in Cu-Cr alloy

In order to compare the effect of Ag and Zr with same atomic ratio on mechanical properties and electrical conductivity improvement of Cu-Cr system alloys, three alloys (CuCrZr, CuCrAg and CuCrZrAg) were prepared. And the mechanical properties and electrical conductivity during different aging process had also been studied. The results showed that the tensile strength of CuCrAg and CuCrZrAg were similar at various aging temperature better than CuCrZr. While the electrical conductivity of CuCrZr was better than others.
