The effect of carbon additions on creep of Fe-25 Al-5 Zr alloy
Original language description
Compressive creep of alloys based on Fe-25 at. % Al-5 at. % Zr with different carbon additions (0.06, 1 and 4 at. %) was studied at temperatures from 700 to 900 °C. Stress exponents and activation energies were estimated. Comparison of the data indicatesthat the strengthening by the Laves phase particles is more effective at larger stresses whereas carbides are probably more important at low strain rates at the temperature of 900 °C. Carbon additions deteriorate creep resistance at the temperature of 700 °C. This result is discussed in terms of the ratio of zirconium to carbon in the alloy. An increase of the creep resistance with increasing ratio Zr:C from 0.8 to 2 is in agreement with the behaviour observed previously in alloys with substantially lower concentrations of zirconium and carbon.
