Abstract The average T ‐matrix approximation is applied for calculations of charge transfer of 3d‐electrons in transition metal alloys. In the dilute limit for Cr‐based alloys the transfer of electrons from Cr produces a surplus of about 1.1 electrons on V sites. Manganese lacks 1.1 3d‐electrons and Fe gives away 2.2 electrons. The values are in reasonable agreement with experimental data. For a concentration c = 0.5 the transfers are about half of the values for the dilute cases: 0.5, —0.5, and —1, respectively. Atomic short range order has only slight influence on the charge transfer. Atomic long range order plays a considerable role and may even change the sign of the transfer when compared with the chaotic alloy case.
