Deformation Processing of Magnetic Hexaferrites for Hc Maximization Through Grain Growth Control
Variations of compressive hot forging were investigated as a means of improving the magnetic properties of commercial barium and strontium hexaferrites. By selecting the proper combination of hot working conditions an intense texture can be attained while minimizing grain growth, Imrpoved magnetic properties are realized by increased remanence, minimization of the decrease of coercivity, and an increased energy product.
