摘要：
The influence of the cadmium on the kinetics of precipitation of the theta' and gamma` phases have been studied for the solid solutions Al-Cu4%-CdO,2% (wt) and Al-Ag20%-CdO,2%(wt). The volume occupied by the theta' and gamma' precipitates is determined by a method based on the microhardness, for the annealing temperatures varying from 200 degrees C to 280 degrees C. The presence of Cd results in an decrease of the incubation time of the first nucleation for the Al-Cu system, and in an increase of this time for the Al-Ag system.
