摘要：
High-temperature tensile and creep tests of a Fe3Al-type iron aluminide with Zr addition were performed. Very pronounced influence of annealing at 1150 degrees 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. (c) 2006 Elsevier Ltd.
