摘要：

The effects of varying Nd-contents on the magnetic properties of Nd12.8+ xFe(81.2-x-y-z)Co(y)Ga(z)B(6) ribbons and the resulting die-upset magnets have been investigated. It was found that the Nd content has a significant effect on both magnetic properties and texture of the die-up set magnets. An optimum Nd content exhibits good texture, while both Nd-lean and excessively Nd-rich Nd-Fe-B alloys lead to unsatisfactory textures. The magnetic properties and texture of the die-upset magnets strongly deteriorated with a further increase in the Nd-content. The thermo-mechanical characteristics and the formation mechanism of two kinds of cracks in backward-extruded ring magnets have also been investigated. (C) 2010 Elsevier B.V. All rights reserved.
