Abstract:Control of microstructure and texture is of critical importance in forming rare earth (RE)-iron-boron particulate suitable for anisotropic polymer-bonded permanent magnets and anisotropic sintered permanent magnets. In this study, the selected approach to controlling grain size, while maintaining texture, is through stabilization and refinement of directional growth in melt-spun ribbons. Varying concentrations of Ag were added to melt-spun ribbons of composition (Y0.55Nd0.45)2.2Fe14B1.1. Effects on microstruct… Show more
“…Previously, the authors proposed that the use of a segregating additive (such as Ag) might be able to refine the grain structure [108]. Ag was added to the alloy in various concentrations and the effects on microstructure were observed.…”
