Microstructure and magnetic properties of CO2 laser surface melted Nd-Fe-B magnets
Abstract
The near-surface microstructure and magnetic properties of permanent magnets produced from hot-pressed melt-spun ribbons of a Nd0.13Fe0.81B0.06 alloy were modified by CO2 laser beam melting. Self-quenching of the molten surface layer at an average cooling rate of ≈104K/s resulted in a stratified structure consisting of a zone of large columnar grains between thinner layers of equiaxed grains. The resolidified material was comprised mostly of …
