Al alloy hardness was studied for additions in the range 0 to 16 wt. pct. Ag. The results indicated a pronounced hardness increase with the silver content and an influence of the quenching temperature. Data obtained from scanning electron microscopy indicated that the formation of silver-rich precipitates, wich change with the quenching temperature, seems to produce the changes on alloys hardness.103-110porAg additionsCu-based alloysMicrohardnessScanning electron microscopyArtigo2-s2.0-2542555955
