文摘

Self-organized rod-like disproportionation microstructures were obtained in Sm₂Fe₁₇ alloy by modifying the hydrogenation disproportionation desorption recombination (HDDR) process. The SmH₂ nanorods are uniformly embedded in a Fe matrix. All the SmH₂ are oriented along the same direction, and show a certain orientation relationship with the Fe matrix. Similar morphology was also observed in the disproportionated products of the NdFe_10.5Mo_1.5 alloy. However, for both Sm₂Fe₁₇ and NdFe_10.5Mo_1.5 alloys, no crystallographic orientation relationship is found between the recombined grains and the corresponding disproportionated products, and there is no crystal texture in the HDDR treated magnetic powders.
