Abstract

PURPOSE: To manufacture a high density sintered body having superior magnet characteristics by adding one or more kinds of metal hydrides such as TiH2 and ZrH2 to alloy power consisting of Co, Cr and the balance Fe followed by compacting and sintering in a reducing atmosphere or a vacuum.
CONSTITUTION: Alloy powder is prepared consisting of, by wt., Co 3W35%, Cr 15W45% and the balance Fe or further contg. one or more among Al, Si, V, etc. 10% or less. To this powder is added 0.5W5wt% of one or more kinds of metal hydrides selected from TiH2, ZrH2, HfH2, NbH2, TaH2 and VH2, and they are mixed and compacted. This green compact is heated in an H2 or inert gas atmosphere and maintained at 600W1,000°C in a vacuum of 10-2W10-3 Torr to decompose the metal hydrides and complete deoxidation reaction. The resulting deoxidized green compact is then sintered at 1,200W1,400°C in a vacuum of 10-3W10-5 Torr or reducing atmosphere such as an H2 atmosphere to manufacture the desired spinodal decomposition type permanent magnet alloy.
