ガスアトマイズ粉末による高機能・高性能材料の実用化

抄録

The gas atomized powder is generally spherical and shows the good flowability, low oxygen content and high tapping density. In addition, because of its good productivity, it has been used as a structural material for a long time by taking advantage of these characteristics. Subsequently, it has been applied as a high-performance material in electronic devices, such as sputtering target discs for perpendicular magnetic recording, shot peening with high hardness media and AM etc. In this paper, the author describes some examples of the practical applications of high-performance materials using gas atomized powders.
