中文摘要	The effects of a partial substitution of Cu for Fe on the structure and magnetic properties of mechanically alloyed Nd8Fe84Ti8 alloys were studied in detail. Compared with Cu-free Nd8Fe84Ti8 alloys prepared by mechanical alloying under the same conditions, the temperature necessary for the formation of the Nd(Fe, Ti)(12) phase decreased from 900 to 750 degrees C with the addition of 3 at.% Cu. The addition of Cu negatively influenced the nitrogenation of the Nd(Fe, Ti)(12) phase. The pretreatment of hydrogenation on the Cu-added alloys at 300 degrees C facilitated the formation of nitrides. With increasing the annealing temperature, the intrinsic coercivity of the nitrides increased until it attained a maximum at 850 degrees C. In the 1 at.% Cu-added alloys annealed at temperatures between 750 and 800 degrees C, the metastable phase Nd(Fe, Ti)(7) was formed. With increasing the annealing temperature, the Nd(Fe, Ti)(7) phase was gradually transformed into the Nd(Fe, Ti)(12) phase. The intrinsic coercivity of the 1 at.% Cu-added nitrides reached a maximum at 900 degrees C. With increasing Cu content, the magnetic properties of the nitrides degraded.
