Abstract

The elastic core effect (i.e. the change of the nearest-neighbour distance b around a solute atom) has been measured in three aluminium alloys [1]. This relaxation of the crystal around the substitutionnal site drives the macroscopic effect which is the change of lattice parameter a. According to Vegard’s law, at least for low concentrations c, the dependence on c is linear. Using the slope (da/ac) we may calculate the host-solute interatomic distance (b+δbCM) via an elastic theory which treats the host crystal as an elastic continuous medium (C.M.) [2,3].
