Properties of Ultrafine Amorphous Fe-Ni-B Powder Produced by Chemical Reduction

Amorphous alloys have properties that differ apparently from those of crystalline materials, such as superior magnetic, mechanical properties and the improved resistance to corrosion. There exist a number of methods of preparing amorphous alloys, of which the most commonly employed one is rapid solidification. Recently, some new techniques have been developed, e.g. chemical reduction. Although fine powder produced by this method was reported in the early literature, it began to attract great attention only after ultrafine
