TEXTURE-FORMATION AND MAGNETIC PROPERTIES OF THE RARE-GROUND METALS

Abstract

The object of investigation: the high-clean rare-ground metals and its binary alloys. The purpose of the work: the investigation of the textureformation processes with the different kinds of the plastic deformation of highly-clean rare-ground metals and its alloys; the investigation of the rare-ground metals deformation mechanisms and influence of the material degree of cleanness on them; studying the anisotropy of the rare-ground metals texturated polycrystals magnetic properties. The probabilities of the formation of the package defect on the basis plane in the clean rare-ground metals (terbium, dysprosium, gadolinium) have been determined. The correlation connection of the package defect probability value with the deformation mechanism and texture conversions in the rare metals has been established. For the first time, the systematic investigations of the texture-formation processes with plastic deformation and the deformation mehcanism of the highly-clean rare metals (terbium, dysprosium, gadolinium) and its alloys have been performed. Examined has been the effect of the material degree of cleanness on the deformation mechanism and texture-formation with the rare metals cold rolling. Studied has been the anisotropy of the magnetic perception of the texturized polycrystals of terbium, gadolinium and dysprosium in the temperature field within 293-700 KAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
