The results indicated that the presence of silver introduces new thermal events ascribed to the formation of a silver-rich phase and, after addition higher amounts than 8 mass% Ag to the Cu-8 mass% Al alloy it is possible to observe the formation of the gamma(1) phase (Al4Cu9), which is only observed in alloys containing minimum of 9 mass% Al. These results may be attributed to some Ag characteristics and its interaction with Cu and Al.759-762engAg-Al interactioncopper-based alloyssilver additionsthermal behaviorArtigo10.1007/s10973-006-7790-0WOS:000244823700028Acesso restrito
