摘要：
Sm-Fe binary alloy with the hard magnetic Sm5Fe17 phase was produced by melt-spinning followed by heat treatment. The magnetic properties of the Sm-Fe melt-spun ribbon depended on the annealing temperature. The highest coercivity, H-i(c) = 1.90 MA m(-1), was obtained by annealing the Sm-Fe melt-spun ribbon for 1 h at 923 K. The coercivity of the Sm5Fe17 melt-spun ribbon was attributed to the grain size of the hard magnetic Sm5Fe17 phase. (c) 2006 Elsevier B.V. All rights reserved.
