Precipitation hardening in the Cu-11 wt.%Al-10 wt.%Mn alloy with Ag addition

In this work the precipitation hardening in the Cu-11 wt.%Al-10 wt.%Mn alloy with Ag addition was studied using different experimental techniques. The results indicated that the hardening on ageing of the Cu-11 wt.%Al-10 wt.%Mn alloy is only due to bainite precipitation, while in the Cu-11 wt.%Al-10 wt.%Mn-3%Ag alloy three reactions in sequence can occur, including the bainite precipitation.
