Abstract
In sintering a metal powder after pressure molding into a given configuration, random amorphous flaky metal fine powders () are used as metal powder materials. In addition, spherical particulate metal powdersare used as main materials, and random amorphous flaky metal fine powdershaving finer particle size than the metal powdersand produced by fracturing a metal fracture material by means of high-velocity gas swirling flow are used as sub-materials, and molding and sintering are performed in a state of dispersing the sub-materials () in the main materials (). Thus, despite being a power metallurgical product, it is possible to obtain a metal product having a dense metallographic structure and excellent in properties such as mechanical strength.
