Abstract

Electron microscopy, x-ray diffraction analysis, Mössbauer spectroscopy, and magnetic measurements are used to establish, study, and systematize 12 basic types of fine crystalline structure (FCS) formed as a result of magnetic decomposition in bcc alloys which are based on the system Fe-Cr-Co (mono- and polycrystalline) and differ greatly in the form and mutual location of regions of strongly and weakly magnetic phases and the associated remagnetization mechanisms and magnetic properties. The conditions and mechanism of formation of each type of FCS are studied. It is shown that it is possible to obtain transitional types of FCS's and that, through the use of different types of FCS's, it is possible to control the parameters of the hysteresis loop.
