Resumo
In this study the effect of Ag additions on the thermal behavior of the Cu-22.55 at.%Al alloy was studied using electrical resistivity measurements, in situ X-ray diffractometry, differential scanning calorimetry, and optical microscopy. The results indicated that Ag additions do not change the phase transformations sequence in the studied alloys, but modify its critical temperatures due to a change on entropy of system. It was verified that at the cooling rate of 10 K/min the decomposition of beta phase into (alpha + gamma(1)) is incomplete, but for lower cooling rates than 1.0 K/min this reaction is completed.
