%X This paper studied the Ni-NbC alloy morphology and orientation character under the effect of impurity Mo, by using optical and scanning electron microscope(SEM)and X-ray preferred orientation analysis. Result has shown that the growing primary crystals have two kinds of morphologies: hexahedron and octahedron, while their preferred growth orientation is <111> and <100> , respectively. During the growth of eutectic alloy, NbC phase branched mainly on the preferred growth direction, while the effect of defect was minor.
