Age hardening in Cu-9Ni-2Sn and Cu-9Ni-5Sn alloys at 573 and 673 K is studied. After an incubation period (+ 10%) strengthening appears which is due to precipitates in the Cu-9Ni-2Sn alloys. On the other hand an immediate increase of the yield stress characterizes the annealing of the Cu-9Ni-5Sn all
