Short-range order (SRO) kinetics of Ag-(3.5, 7.5, 11.5, 15.5) at.% Al have been investigated by measurement of electrical resistivity during isochronal and isothermal annealing. Besides an increase of the atomic mobility with increasing Al-content the samples show a reduction of resistivity with increasing degree of SRO. After a small and sudden temperature change the new equilibrium state of SRO is adjusted by a simple relaxation process with an activation energy of 1.37 ± 0.1 eV. The microstructure of short-range ordered α-AgAl is therefore assumed to be homogeneous.
