A model is introduced for the description of the atomic structure of amorphous metal–metalloid alloys. The model is based on the assumption that the local arrangement of the atoms in the amorphous state is similar to that in the corresponding crystalline phase. Short‐range order of the Fe 3 C and Ni 3 P structure types is used for modelling amorphous metal–metalloid alloys. The partial and the total pair distribution functions are calculated and compared with experimental values. The Ni 3 P unit cell is suitable as a structural unit for modelling the amorphous atomic structure. The Fe 3 C unit cell is not realized as a structural unit in amorphous metal–metalloid alloys in general.
