Abstract
The properties and microstructure of iron aluminide Fe28Al4Cr after hot rolling can be modified by heat treatment at 700 or 800 °C and by suitable alloying, for example by cerium. The ductility, hardness and structure of Fe₃Al-based alloys with and without cerium addition were determined and compared after hot rolling. The formability of Fe28Al4Cr is compared with steel 12 060 to find suitable rolling temperature.

Key words
