Purpose: The major problem restricting universal employment of intermetallic phase base alloy is their low plasticity which leads to hampering their development as construction materials. The following work concentrates on the analysis of microstructure and plasticity of ordered Fe3Al D03 - structured alloy containing 28% at. of Al and 5%Cr at. during hot plastic deformation process. Design/methodology/approach: After casting and annealing, alloy specimens were subjected to axial-symmetric compression in the Gleeble 3800 simulator at temperatures ranging from 600 to 1200 degrees centigrade at 0.1, 0.01, 1.0, 10 s to the -1 strain rates. 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 microscopy. Findings: The processes of structural reconstruction such as dynamic recrystallization, which take place during hot-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 obtained are vital for designing an effective thermo-mechanical processing technology for the investigated Fe3Al-5Cr alloy.
