A Dilatometric Study of the Alloys of the Al-Fe System

Abstract

The paper presents the results of the dilatometric study of alloys based on the Al-Fe system. The alloys were obtained by classic casting technique. The studies were carried out on samples after casting and annealing. Phase transformation and thermal expansion investigations of the alloys from the Al-Fe system with Al concentration of 38 and 48% at. are discussed. The linear thermal expansion α was calculated by standard method. The α coefficient as a temperature function was noticed. The knowledge on the phase transformations in these alloys including the information about order-disorder transition is very important from the point of view of obtained mechanical and physical properties of alloys of the Al-Fe system. The results are a valuable supplement for development of knowledge of these alloys.
