The cast piece is placed in a vessel into which H2 gas is fed at 200Torr-50kg/cm<2> to produce a collapsed alloy powder which is then subjected to dehydrogenation. Consequently, a coarsely crushed powder powder having average particle size of 10-500μm is obtained and admixed with 0.02-5.0wt.% of a lubricant. Finally, it is subjected to jet mill crushing in an inert gas flow to produce a fine powder having average particle size of 1-5μm.  This method produces a powder having uniform particle distribution efficiently and the magnetic characteristics of a magnet alloy is enhanced.
