Structure of an Amorphous FePC Alloy

The structure of an amorphous Fe80P13C7 alloy obtained by rapid quenching from the liquid state has been studied by X‐ray diffraction. An analysis of the radial distribution function indicates that the first four nearest neighbors are located at distances of 2.6, 4.3, 5.1, and 6.7 Å. The number of the first nearest neighbors is 13.1 and is dominated by FeFe atom pairs. The structure of the alloy can be described by a randomized b.b.c. iron in which the iron atoms have the first nearest neighbor number 13.6 at a distance of 2.6 Å.
