Influence of silver additions on the Cu-13 wt pct Al alloy hardness.
MetadataShow full item record
The influence of silver additions on the Cu-13 wt. pot. Al alloy hardness was studied for additions in the range 0 to 16 wt. pot 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.
