Abstract

Abstract: In this paper, effects of Smtla, Fe and Cu of directional Solidification ailoys in Sm-La-Co-Fe-Zr System on 0 have been studied. 0 is defined as the angle of constrained crystal growing direction with easy axis of the alloys. SPACE A is found only an area of compositions Where θ is equal to 0 ° , and where the magnetic inductions of the alloys are high enough to be useful in engineering. Compared with 2/17 type, 1/5 tpye of sintered RE-Co permanent magnets, a new kind of directionally solidified ones developed, in SPACE A, is more ductile and suitable for an segregating unit.

Key words: directional solidification, rare earth cobalt, rmanent magnets, segragating unit
