Purpose: Limitation on the capacity for a wide application of intermetallics from the Fe-Al system results from their insufficient plasticity. It is a factor which inhibits further development of intermetallics as constructional materials. Under this study, research has been conducted on the capacity for forming alloys based on intermetallic phases from the Fe-Al system, via thermo-mechanical processing. Design/methodology/approach: After casting and annealing, alloy specimens were subjected to axial-symmetric compression in the Gleeble 3800 simulator in the range of 600-1200 degrees centigrade. In order to analyse the processes which take place during deformation, the specimens after deformation were intensely cooled with water. Structural examination was carried out using light and electron microscopy. Findings: The capacity for alloys' hot deformation and limited plasticity of an alloy in ambient temperature have been shown. In addition, the processes of structural reconstruction, which take place during and after deformation, have been detected. Practical implications: The research carried out enabled the understanding of the phenomena taking place during deformation and annealing of the investigated alloy. The results will constitute the basis for modelling the structural changes. Originality/value: The results will be used to design the basis for a thermo-mechanical processing technology via rolling and inter-operational annealing of the investigated compound with an intermetallic Fe-Al phase matrix.
