| 简介 |
PROBLEM TO BE SOLVED : To obtain an alloy capable of controlling the dispersion of magnetic properties and further improving magnetic properties by preparing a permanent magnet alloy, particularly Sm-Co alloy, in which distances between leading phases of the whole ingot are properly arranged and segregation is reduced. SOLUTION : Centrifugal casting is performed under the condition of <=0.5cm/ sec average accumulation rate, by which the permanent magnet alloy having a structure in which the distances between leading phases of the whole ingot are regulated to <=200μm is obtained. |
