Abstract

In the present study, the yield strength of 80% cold-rolled and aged Cu–3Ag–0.5Zr alloy was theoretically estimated for five strengthening mechanisms using data obtained from optical microscopy and transmission electron microscopy. For comparison, the mechanical properties were evaluated in different conditions. The theoretical yield strength was in good agreement with the experimental value. The major contribution to yield strength in cold-rolled and aged condition was from coherency strengthening and dislocation strengthening.
