| Abstract: | Magnetic properties and phase evolution of melt spun R 9.5Fe bal.Ti 2B 10 (R = MM(A), MM(B), MM(C), Pr, Nd, Ce, and La) nanocomposites have been investigated. Based on the results for the X-ray diffraction and thermal magnetic analysis, only 2:14:1 and α-Fe phases appear for R = MM(A) and Pr, and an additional Fe 3B phase is present for R = MM(B), MM(C), Nd, and Ce. Besides, the uniform fine grain size of 20-40 nm is almost unchanged for the ribbons with various rare earth elements. Accordingly, magnetic properties of MM 9.5Fe bal Ti 2B 10 nanocomposites are mainly dominated by the composition of Mischmetals or the rare earth elements adopted, and are consistent with the outcome for the combinations of magnetic properties of their corresponding R 9.5Fe bal Ti 2B 10 nanocomposites. In this study, the optimum magnetic properties of B r = 9.3 kG, iH c= 12.1 kOe and (BH) max = 18.0 MGOe can be achieved for MM(B) 9.5Fe bal Ti 2B 10 nanocomposites. They not only exhibit comparable magnetic properties to the commercial available powders but also reduce the original material cost effectively. ? 2011 American Scientific Publishers. |
