    摘要： A powder metallurgical method for fabricating a high-density soft magnetic metallic material comprises steps of providing an initial powder; using a spray drying process to fabricate the initial powder into a spray-dried powder; placing the spray-dried powder in a mold and compacting the spray-dried powder under a compacting pressure and a compacting temperature to form a green compact; and sintering the green compact at a sintering temperature to form a soft magnetic metallic material. The spray-dried powder, which is fabricated by the spray drying process, has superior flowability, compactability and compressibility and is suitable for the press-and-sinter process. The soft magnetic metallic material fabricated by the present invention is outstanding in sintered density and magnetic performance. The present invention adopts the inexpensive press-and-sinter process and has a low fabrication cost.

    摘要： A method of producing a workpiece is disclosed. The method includes: providing a first powder, a hardness of the first powder being less than 250 HV, and a mean particle size of the first powder being less than 20 μm; mixing the first powder and a second powder to form a mixed powder; the mixed powder includes carbon, chromium, iron, and elements selected from the group consisting of molybdenum, nickel, copper, niobium, vanadium, tungsten, silicon, cobalt, and manganese; adding a binder and water to the mixed powder; applying a spray drying process to granulate the mixed powder to form a spray-dried powder; applying a dry pressing process to the spray-dried powder to form a green part; applying a debinding process to the green part to form a debound body; and sintering the debound body into a workpiece having a hardness of higher than 250 HV.
