Conclusions
We studied the particle distribution of powders of highly coercive multicomponent alloys on the basis of the compound samarium-cobalt as to shape, dimensions, and intensity of magnetization; we examined the dependences of the grain size distribution of the powders on the time of comminution. It was established that the particles have predominantly the shape of parallelepipeds, cubes, tetrahedrons (approximately 30, 20, and 20%, respectively), and that their content depends only very slightly on the time of comminition. The powder contains particles (about 5%) whose vector of magnetization is perpendicular to their major axis; this makes it more difficult to obtain a uniaxial texture and high density of the compacts.
