摘要： A method for compacting powders for powder metallurgy comprises packing powders for powder metallurgy formulated with a lubricant in a compacting die applied with a lubricant on inner wall surfaces thereof, and subjecting the powders to warm or hot compaction. The powders contain the lubricant in an amount up to 0.2 wt %, non-inclusive of 0%, based on the total of the powders and the lubricant.

摘要： Disclosed is a method for the compaction of a soft magnetic powder capable of manufacturing a green compact which has attained high density and high strength, is excellent in mechanical properties and magnetic properties, and does not cause a reduction in electrical resistance. Soft magnetic powder particles individually surface-coated with an insulating vitreous layer containing P, Mg, B, and Fe as essential components are used, and a lubricant is applied to the inner wall surface of a compaction die. The soft magnetic powder is subjected to compaction at from not less than room temperature to less than 50° C. without mixing the lubricant with the soft magnetic powder, followed by annealing at from 50 to 300° C.
