Title: Fei Du: Innovator in Rare Earth Alloys and Magnets

Introduction

Fei Du is a prominent inventor based in Beijing, China. He has made significant contributions to the field of materials science, particularly in the development of rare earth alloys and magnets. With a total of 2 patents, his work has garnered attention for its innovative approaches and practical applications.

Latest Patents

Fei Du's latest patents include a method for preparing fine grain rare earth alloy cast strips and a rotary cooling roll device. The preparation method involves a melting process where the power of an induction melting furnace is controlled to perform a cyclic heat treatment. This ensures that the alloy raw material is completely melted before reaching a surface temperature of 1300° C. After melting, the power is adjusted to stabilize the surface temperature between 1400° C. and 1500° C. The casting cooling process then cools the melt on a rotary cooling roll, achieving an alloy cast strip with a controlled surface linear velocity of 1.5 m/s to 2.25 m/s. Additionally, he has developed a NdFeB rare earth magnet that features a main phase and distinct grain boundary phases, with specific area percentages for the white and gray grain boundary phases.
