摘要	A novel grain refiner composed of nickel, tungsten and yttria was prepared by the powder metallurgy way. The microstructure of the refiner alloy was studied by optical microscope (OM), scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). The refinement process was simplized. It was shown that the alloy grains could be refined by addition of the refiners apparently even at high pouring temperature. The average grain size of the refiner free alloy was 4 mm, and 0.4 mm for the refined alloy. The fine-grain superalloy has excellent mechanical properties at intermediate temperature. The refinement mechanism was discussed:
