Analysis of the Mechanically Alloyed Fe85-Nb5-B10 Powder Using a Non-unique Lattice Parameter

X-ray diffraction patterns of mechanically alloyed Fe85Nb5B10 powder were fitted using whole powder pattern decomposition procedure to resemble the presence of α-Fe type crystals with different Nb content. To do so, a distribution of lattice parameters was proposed based on the asymmetry of the diffraction maxima and the broadening of the distribution of the powder particles composition. Analogously, a set of discrete sextets was used to represent the different local Fe environments.
