Description	The influence of chemical composition on the deformation resistance of iron aluminides was studied by the plastometric tests on three types of Fe – 40 at. % Al based materialsalloys; especially the influence of zirconium and boron, respectively effect of fine TiB2 particles addition was investigated. All materials were prepared using the identical procedure. The samples were pre-heated to a temperature of 1200 °C and then deformed at temperatures from 800 to 1200 °C, the nominal strain rate was 0.05 s-1, 0.4 s-1-1, 4 s-1 and 30 s-1. The relationship describing the maximum deformation resistance of aluminides depending on the temperature-compensated strain rate was derived from obtained data. The values of activation energy and hot deformation resistance of the studied materials were compared and the differences interpreted in terms of physical-metallurgical effects of additives.
