Using an effective‐medium model for the electrical resistivity the Boltzmann equation is solved for binary systems including spherical precipitates. The model reproduces the behaviour of the resistivity of aluminium alloys during ageing and particularly provides the correct position of the characteristic resitivity maximum. Compared to the former generalized‐effective‐medium theory the two parameters mean free path and extra‐resistivity caused by clustering are involved in a more realistic way.
