| 中文摘要 | The effect of pressure on the microstructure of alpha -Fe/Sm-2(Fe, Si)(17)C-x nanocomposite magnets has been studied by annealing amorphous Sm8Fe85Si2C5 alloy under pressures up to 6 GPa at 923 K. The high-pressure experiments were carried out in a belt-type apparatus. Experimental results show that, with increasing pressure from normal pressure to 6 GPa, the grain size of the alpha -Fe and Sm-2(Fe, Si)(17)C-x phases in the alpha -Fe/Sm-2(Fe, Si)(17)C-x nanocomposites decreases, from 30.6 to 6.4 nm for the former and from 28.7 to 5.8 nm for the latter. The volume fraction of Sm-2(Fe, Si)(17)C-x increases as pressure increases. The alpha -Fe/Sm-2(Fe, Si)(17)C-x nanocomposite magnets prepared under 4 GPa have a significant increase in both coercivity and remanent magnetization as compared to those prepared under normal pressure.
