Abstract
PURPOSE:To improve dimensional accuracy and yield by annealing an iron-cobalt sintered alloy at the specific temp. lower than the sintering temp. after sintering and sizing-treating the alloy, successively rapid-cooling and cold-working. CONSTITUTION:The sintered material of iron-cobalt series alloy is sizing-treated to correct deformation of warp, etc. Next, the sintered material is annealed at the temp. which is lower than the sintering temp. and higher than the transformation temp. of alpha.gamma phase. After becoming the room temp. by rapid-cooling, various kinds of cold workings, such as boring, groove cutting, are executed. By this method, electro-magnetic parts having high accuracy can be produced with iron-cobalt sintered alloy.
