Abstract

AN anomalous increase in resistivity has been observed during formation of G. P. zones (clusters rich in solute) in several aluminium alloys1,2. Mott3 suggested that this effect may be due to a critical scattering of the conduction electrons when the zone grows to dimensions of the wave-length of the conduction electrons. Matyas4 showed on theoretical grounds that a maximum should occur for the resistivity change during zone formation.
