The Influence of Carbon on Small Punch Testing of Niobium-alloyed Iron Aluminide
Original language description
Iron-aluminium-based alloys are promising candidates for various applications at high temperatures. Unfortunately, creep resistance of these alloys is relatively low. It could be improved by introducing second-phase particles, e. g., by additions of carbon and carbide forming elements. On the other hand, the presence of carbides can influence ductility of the alloys with enhanced creep resistance. In the present study, the effect of niobium and carbon additions on the ductility of a Fe3Al-type alloy isinvestigated. The constant-deflection mode of the small punch test is used to compare fracture properties and their temperature dependence in the alloy with different amounts of carbon. It is shown that both the fracture energy and the deflection at maximum load are greater in the alloy with the greater carbon and that the ductility is not reduced by the presence of niobium carbides. The ductile-to-brittle transition temperature closely correlates with the temperature of phase transforma
