| 中文摘要 | The structure, phase transformation, and magnetic properties of mechanically alloyed (MA) [Pr15Fe85-mCm] (m = 9, 10, 11) samples have been studied systematically. Pr2Fe14C can be formed within certain composition (m greater than or equal to 10) and temperature (from 750 degrees C to 900 degrees C) ranges. Isothermal annealing of [Pr15Fe74C11] at 750 degrees C for different lengths of time reveals that the formation of Pr2Fe14C is a nucleation and growth process; excessive prolongation of the annealing time causes the decomposition of Pr2Fe14C and Pr2Fe17Cx into carbide and alpha-Fe. Hexagonal Pr2Fe2C3 (a = 8.66 Angstrom, c = 10.40 Angstrom) and the fee Pr-rich phase (a = 5.2 Angstrom) are formed in the alloys. The best magnetic properties are achieved for [Pr15Fe75C10] alloy annealed at 900 degrees C for 35 minutes, which contains Pr2Fe14C, Pr2Fe17Cx, alpha-Fe, Pr2Fe2C3, a Pr-rich phase, and Pr2C3. |
