Abstract
Permanent magnets are prepared by a method comprising mixing a particulate rare earth-iron-boron alloy with a particulate additive metal powder, compacting the aligned mixture to form a shape, and heating the compacted shape at a temperature at least 150.degree. C. less than the sintering temperature of a rare earth-iron-boron alloy and usually in the range from about 700.degree. C. to less than 850.degree. C.
