Abstract

The precipitation of the Guinier-Preston zones in Al4,65at.% Ag(15%wt.), studied using an electrical resistivity measurements technique during an isothermal aging, follows a nucleation, growth and coarsening stages. The particles growth obeys the JMAK law while their coarsening, the LSW theory. The diffusion coefficient of the solute atoms, during the GP zones formation at 125°C, is in the order of (8,69 ± 2,17).10-21m2/s. The electrical resistivity of the alloy results from the contribution of the Guinier-Preston zones and that of the matrix. Due to the weak Guinier-Preston volume fraction, the electrical resistivity of the alloy is essentially due to the matrix contribution.
