| heal.abstract | The magnetic and microstructural properties of melt-spun Nd18Fe76-XGaXB6 alloys have been studied as a function of Ga content. Coercivities of 17 kOe were obtained in underquenched samples having a large grain size of 500 nm. Samples prepared at wheel speeds of 15-19 m/sec, as well as overquenched (40 m/sec) and subsequently annealed, gave coercivities of around 20 kOe with no significant improvement of H-c upon Ga substitution. In Ga-free samples prepared by annealing highly overquenched ribbons (at 60 m/sec) only moderate coercive fields could be achieved (14 kOe). These samples had grain sizes of 70-100 nm. However Ga substituted samples prepared under the same conditions have a fine grain structure consisting of unequiaxed grains with size around 20 nm and show coercivities up to 23 kOe. | en |
