Abstract

The effect of 2% Ag addition on the kinetics of eutectoid decomposition in the Cu-9wt.%Al alloy will be studied using optical and scanning electronic microscopy, differential thermal analysis, X-ray diffraction, energy dispersive X-ray analysis and microhardness changes measurements with temperature and time. The results obtained for the alloy with Ag addition will be compared with those obtained for the Cu-9%Al alloy, to analyse the Ag effect on the eutectoid decomposition mechanism.
