Creep of Fe3Al alloys with addition of vanadium
Original language description
Additions of carbon and carbide-forming elements can positively influence high temperature mechanical properties of alloys based on Fe3Al intermetallic compound. In the present study, the effect of vanadium and carbon additions on creep resistance of Fe3Al-type alloys is investigated. The alloys contained (atomic %) (i) 27.0 % Al, 1.17 % V, 0.02 % C and (ii) 27.0 % Al, 1.13 % V, 0.73 % C (Fe balance). Creep was tested by uniaxial compressive tests at constant load with stepwise loading: in each step, the load was changed to a new value after steady-state creep rate had been established. The applied stress dependences of the creep rate at different temperatures were analyzed in terms of stress exponent n and activation energy Q. The constant-deflectionmode of the small punch test was used to estimate other mechanical and fracture properties and their temperature dependence. The yield force and the maximum force were evaluated from the force vs. deflection dependence and compared with t
