Abstract
Fe-28Al-3Cr (at.%) alloy with small amounts of Ce, C and Mn additives was tested in creep under constant load ranging from 20 to 280 MPa at temperatures of 500, 600 and 700 °C. The effect of high temperature annealing (1150 °C) on creep characteristics (creep rupture life, creep rupture strength, minimum creep rate, etc.) was investigated. The improvement of creep properties is supposed to be due to the solid solution and/or precipitation hardening. The proportion of both is substantially enhanced by solution annealing and subsequent precipitation during cooling to room temperature.

Key words
iron aluminides, creep properties
