Career Trajectory
Bio
Through the discovery of the three characteristics of amorphous alloys - their high strength and toughness, high corrosion resistance and soft magnetism - in the late 1960s, Dr. Masumoto exploited the new field of materials science based on amorphous metal. In particular he is a pioneer in creation of the new single-roll method, which makes continuous mass production of wide ribbon amorphous alloy possible, (succeeded in 1976). This led to a tremendous increase in the industrial production of amorphous alloy, the historical significance of which is remarkable. In the course of the research, in 1973, both Dr. Masumoto and Dr. Fujimori cooperated in the develop-ment of zero-magnetostriction CoFeSiB and high saturation magnetization FeSiB type alloys that are representative of soft magnetic alloys and the new type magnetic materials that virtually developed magnetic industry. Backing by the Research Development Corporation of Japan from 1975 onwards led to successfully commissioned development work, increasing momentum for applications of amorphous alloy in Japan, and magnetic materials in particular. These results have led to the current mass production of a wide variety of practical products centered on magnetic cores for switching power supplies. Amorphous alloy produced using the single-roll method has currently reached 100,000 tons annually, with the total value of production of applicable products exceeding one trillion yen globally. From an energy efficient perspective, amorphous alloy magnetic cores used in transformers are receiving attention as a method to combat recently escalating environmental issues. Demand is increasing rapidly in Japan, Europe and America, and even countries such as China and India. It is with these reasons that Development and Industrial Contribution of Amorphous Alloy by both Dr. Masumoto and Dr. Fujimori has been selected as the 9th Yamazaki-Teiichi Prize Winner in the Materials Segment.
