Abstract
Low temperature specific heat measurements have been performed on disordered Fe1-cAlc samples in the concentration range 0.10 ≤ c ≤ 0.50. A drastic difference between the « electronic » specific heat of the disordered and ordered samples is observed. This observation joined to the recent knowledge on the particularly complex phase diagram led to reconsider the results obtained about the physical properties of the FeAl alloys. A qualitative review of some physical properties, namely the specific heat, magnetic susceptibility and magnetization, show that these properties depend strongly upon the state of the system at a given concentration. The annealed (ordered), quenched (partially ordered) and cold-worked (disordered) states of samples are used to investigate the ordering effectsKeywords
