| 摘要 | The Ni-33Al-28Cr-6Mo-0.3Hf near eutectic alloy was treated in a 10 T strong magnetic field at 1073 K and 1173 K for 1.5 h respectively. Microstructure examination reveals that after the strong magnetic field treatment, most Ni(2)AlHf Heusler particles have changed into Hf solid solution, and moreover Hf solid solution and Heusler particles along eutectic cell boundaries distribute more uniformly. In addition, the eutectic cellular microstructure of the alloy with strong magnetic field treatment at 1173 K is changed greatly. The eutectic cell has an obvious disintegration and Cr(Mo) plates become coarsening and spheroidizing. The compression tests show that room temperature compressive ductility of the alloys with strong magnetic field treatment improves significantly, compared with the heat-treated alloy.
