	Mechanosynthesized Co x Fe 1-x-y Ni y alloys were examined using X-ray diffraction (XRD) and Mössbauer spectroscopy. In order to explain the shape of hyperﬁne magnetic ﬁeld (HMF) distributions for the alloys,a local environment model based on a multinomial distribution was proposed. The model was in agreement with the XRD data and conﬁrmed that the studied alloys were dis-ordered solid solutions. It was successfully applied to describe the samples with bcc and fcc crystalline lattice type within the relatively broad range of component concentration. The results showed that the change of the crystalline lattice type does not cause an abrupt change of the HMF value. Moreover, a mean number of unpaired spins for the ﬁrst coordination sphere may be used as aparameter to describe the HMF value experienced by 57 Fe nucleus. Finally, a set of the most probable atomic conﬁgurations and their corresponding contributions to the HMF distribution were obtained.
