| Abstract | The microstructure and creep behavior of a DS NiAl-Fe(Nb) multiphase intermetallic alloy have been investigated. This alloy exhibits dendritic structure, in which dendritic arm is beta-(Ni,Fe)(Fe,Al) phase surrounded by interdendritic region of gamma'/gamma phase. The results of the creep test indicated that all of the creep curves have similar characteristic, which is a short primary creep stage and a dominant steady state creep stage, and the creep strain ranges from 18% to 52%. The apparent stress exponent and the apparent activation energy were analyzed and discussed. The. mechanism of the creep deformation was also analyzed by the observation of TEM. |
