The compressive properties of Fe-25Al-10Ti intermetallic alloy were studied as a function of temperature and strain rate. Optical microscopy and transmission electron microscopy (TEM) were used to examine the deformation microstructure. The alloy exhibited strong tendency of strain hardening at low temperatures. A positive temperature dependence of strength was observed in the 673 - 873 K range. The mechanical behavior was interpreted in terms of dislocation structures. Based on the analysis of the stress-strain response, strain rate sensitivity and deformation microstructure, possible hot working range was proposed.
