摘要
The influence of additions of 1.3, 2.5, 3.8, 5.1, and 6.3 at.% Ag on the aging behavior of the Cu-10.4at.%Al alloy was studied using microhardness measurements, scanning electron microscopy (SERI) and energy dispersive X-ray (EDS) analysis. The results indicated that with silver additions it is possible to obtain a response to age hardening, and that for large aging times there is a decrease in the alloy hardness, with a process that lends to Ag and Al segregation.
