Abstract

Using microhardness and electrical resistivity measurements, the contributions of the matrix and that of the Guinier-Preston zones to the hardening and to the electrical resistivity of the Al10at.%Ag alloy are determined separately during the Guinier-Preston zones precipitation. A linear correlation between the hardness and the electrical resistivity of the as quenched alloys exists. There is also a linear relationship between the contribution of the matrix to the hardening and that to the electrical resistivity of the isothermal aged alloy. However, no linear relation exists between the hardness and the electrical resistivity of the isothermal aged alloy.
