Description

Phase composition of powder FexAlx-1 alloys prepared by self-propagated high temperature synthesis (SHS) and atomic rearrangements in B2 FeAl due to varying Al concentration and annealing have been investigated by X-ray diffraction (XRD) and 57Fe transmission Moessbauer spectroscopy (TMS). It has been established that phase composition of FeAl alloys is basically close to equilibrium phase diagram. However, some phases showed deviations from stoichiometric composition. Atomic arrangement in B2 FeAl phase demonstrated strong dependency on Al content in alloys. Some peculiarities of B2 FeAl atomic arrangement in SHS prepared FexAlx-1 alloys have been observed and discussed
