There are many ways to make powder, and the shape of the powder produced by each method is not all spherical, so the so-called powder diameter and the "equivalent diameter" of the powder refer to different measurement methods. There are different values, some take the diameter of the spherical powder equal to the volum……

The size control of powder metallurgy parts is often affected by the uniformity of the powder filling. Due to the unevenness of the powder filling and the uneven density of the green embryo, the shrinkage rate after sintering is uneven. Is there any way to improve it? 1. Powder with good fluidity should be used as much……
