  • Method of making magnets
    Patent number: 3977918
    Abstract: A method of making an integral toroidal magnet comprising the steps of compacting suitable magnetic powder material into a toroidal shape while subjecting it to a particle aligning magnetic field, hot pressing the compacted powder toroid in a confining die at a temperature and pressure sufficient to cause shrinkage of the toroid in the axial direction and provide a packing density greater than 93% of the theoretical maximum value and substantially unidimensional shrinkage, heat treating the toroid at a temperature sufficiently higher than the hot pressing temperature to achieve an enhanced crystallographic alignment equivalent to the alignment obtained by sintering, annealing the toroid at a temperature sufficiently lower than the heat treating temperature to provide a magnetic coercivity similar to the coercivity achieved by annealing after sintering, and magnetizing the heat treated toroid in the direction of crystallographic alignment.
