Abstract
	The aim of this work is to study the possibilities of hot plastic deformation of the FeAl intermetallic alloys. Iron aluminides, as we now, has poor ductility at room temperatures. One way of their forming is at medium and at high temperature plastic deformation with specially process conditions. We investigated the Fe-Al alloy of 38%at. Al with a structure of ordered B2 type. It was deformed at the range of temperatures of 800? C to 1250 C? with a step on 100°C, by means of compression. Compression tests was performed on Gleeble 3800 simulator up to the assumed value of the deformation ?=1,2. Influence of the parameters of the hot deformation process (temperature and strain rate) on the mechanical properties during the compression have been analyzed. The relations between the parameters of the deformation process (Zener-Holomon’s parameter) and the mechanical properties during the compression test was determined.  The analysis of the structure before and after the deformation process was performed with the use of LM technique. Changes in the structure of the alloy, which are typical of the recovery process and dynamic recrystallization, indicating a wide range of possibilities of plastic forming have been revealed. We confirm that the optimally parameters of the hot deformation process influenced on the process of the dynamic rebuilding of the structure which is responsible of the good plasticity.
