摘要： A method of forming a cylindrical compact for a cylindrical magnet is improved by moving a core pin and a die of a mold at the same time of pressing magnet materials with a pressing punch in the same direction as that of the pressing punch at travelling speed Vc and Vd indicated by following equation:Vc=m.multidot.Vp(0.5.ltoreq.m.ltoreq.1.0)Vd=n.multidot.Vp(0.5.ltoreq.n.ltoreq.1.0)where Vc is the travelling speed of the core pin, Vd is the travelling speed of the die and Vp is the pressing speed of the pressing punch. It is possible to form the thin-walled elongated cylindrical compact by utilizing the frictional force caused between the mold and the magnet materials for forming the compact very effectively in order to obtain a thin walled elongated cylindrical magnet.

摘要： The ability to hot work RE-Fe-B type compositions to form anisotropic magnets containing Nd.sub.2 Fe.sub.14 B.sub.1 -type crystal grains is improved by the addition of suitable, small amounts of one or more of cerium, lanthanum or yttrium. The improvement in hot working is seen in the reduction of cracks in the deformed body and in the ability to reduce the hot working temperature without a significant penalty in magnetic properties.
