Abstract :
High-temperature tensile and creep tests of a Fe3Al-type iron aluminide with Zr addition were performed. Very pronounced influence of annealing at 1150 °C/2 h namely on creep properties (time to rupture – TTR, and minimum creep rate – MCR) was observed. The nature of dislocation obstacles was described using TEM. The behaviour of the material was explained by a combined effect of solid solution and precipitation hardening.
