Abstract: Provided are a method for producing powder for a magnet, and methods for producing a powder compact, a rare-earth-iron-based alloy material, and a rare-earth-iron-nitrogen-based alloy material. Magnetic particles constituting the powder each have a texture in which grains of a phase of a hydride of a rare-earth element are dispersed in a phase of an iron-containing material. The uniform presence of the phase of the iron-containing material in each magnetic particle results in powder having excellent formability, thereby providing a powder compact having high relative density. The powder is produced by heat-treating rare-earth-iron-based alloy powder in a hydrogen atmosphere to separate the rare-earth element and the iron-containing material and then forming a hydride of the rare-earth element. The powder is compacted. The powder compact is heat-treated in vacuum to form a rare-earth-iron-based alloy material. The rare-earth-iron-based alloy material is heat-treated in a nitrogen atmosphere to form a rare-earth-iron-nitrogen-based alloy material.

Abstract: A method for preparing an ultra-long-tube type fine-grain molybdenum tube target uses molybdenum powder with the purity being greater than 3N to prepare a target tube with a uniform wall thickness, where the length is 1700-2700 mm; the diameter is greater than 150 mm; and the wall thickness is 15-40 mm. The method includes: taking molybdenum powder, feeding the molybdenum powder into a film, molding by static pressing, placing in a medium frequency furnace, performing hydrogen sintering to form a tube blank, placing into a mold, forging the mold of a tube target, placing into tempering furnace, annealing, forming fine-grain structures, fine processing, washing, and drying to prepare a molybdenum tube target. The method overcomes defects of a sintering process and a forging process, and relates to simple processes, easy industrial production and control, reduced pollution, reduced cost, improved quality, and remarkably improved production efficiency.
