摘要

The creep behaviour of the intermetallic Fe–28Al–3Cr alloy with Ce additive was investigated at temperatures from 500 to 900°C. The effect of the thermal processing was studied. The properties (e.g. time to rupture, minimum creep rate (MCR), the ultimate deformation) were improved by introducing small particles originating in the temperature interval from 600 to 800°C.
