【 摘 要 】

Rare-earth permanent Nd-Fe-B magnets are the most promising ones because they have the highest magnetic and operating characteristics. These magnets are produced from alloys having the respective chemical composition principally by the powder metallurgy technology. The paper presents the results of study of the manufacturing process of high-quality permanent magnets by the method of solid-phase alloying of magnetic alloys obtained by means of the out-of-furnace fluoride technique. In the present work, metallic foundry alloys and alloy hydrides of Nd-Fe, Dy-Fe and Tb-Fe systems are considered as alloying additions.
