Description	Alloy with chemical composition of Fe-38Al-0,2Mo-0,05Zr-0,1C (in at. %) was studied. The alloy was melted in a vacuum induction furnace using a vacuum of 0.5 Pa and a spinel MgO#Al2O3 melting pot. The melt was cast to the preheated graphitic mould. Threefold refining re-melting for the purpose of the alloy's homogenization and removing of contamination was applied. Thus obtained content of oxygen and hydrogen of 38 ppm, resp. 0.2 ppm enabled to apply hot forming on this alloy. The as-cast microstructurecomprises the FeAl-phase grains of mean diameter about 100 #m with occurrence of dispersive phases at grain boundaries as well as inside the grains. Following annealing 1273 K/24 hours yields in the chemical composition homogenization and annihilation o f former dispersive phases.
