FRACTAL INVESTIGATION OF THE MICROSTRUCTURE IN Alnico8 THERMOMAGNETICALLY TREATED

1. IntroductionAlnico alloys attracted much attention due to their excellent magnetic stability andgood comprehensive properties in the past years. A decade years before, considerableinterest has arisen concerning the chemical compositions of the Fe--Co and Ni-Al richphases which result from the spinodal decomposition of a bee single phase solution athigh temperaturesl'--']. However, emphasis has been seldom placed on kinetics of microstructural evolution occurring within the decomposition t…
