Abstract：[(Nd0.76Pr0.24)1-xCex]12Fe79Al3B6 (x = 0~0.3) series melt as-spun ribbons with diffrent Ce content were prepared,
and their microstructures and magnetic properties were investigated. The experimental results show that the
magnetic properties of the as-spun ribbons decrease with the increasing of Ce content, however, abnormal increases
appear for the x = 0.2 ribbon with Hcj=8.38 kOe, Br=8.68 kGs and (BH)max=14.42 MGOe. HRTEM/EDS results reveal
that the average grain size of the x = 0.2 as-spun ribbon is about 28 nm, which is the most uniform and finest
among all the ribbons, and the grains of the 2:14:1 phase possess significantly high component fluctuation, indicating
that phase separation has occurred. The abnormal increases in magnetic properties of the x = 0.2 as-spun ribbon
is mainly contributed to both the grain refinement and the phase separation.
