摘要	The microstructure and compression behavior at room temperature of a rapidly solidified NiAl(Mo) Hf eutectic alloy fabricated by water-cooled copper mold method were studied by a combination of SEM. EDs and compressive tests. The rapid solidification results in a shift in the coupled zone for the NiAl Cr(Mo) Hf alloy towards the side of Cr(Mo) phase. So the volume fraction of primary NiAl dendrite is increased which is detrimental to the mechanical behavior. On the other hand, the refined microstructure and fine dispersion Heusler phase by Ni(2)AlHf are beneficial to the improvement of mechanical properties. As a result, the strength increases by 10% and the compressive ductility increases by two times at room temperature, when compared with those of the as east state.
