Therefore, metallography of powder metallurgy parts usually includes checking for specific porosity. In process control, metallography of powder metallurgy parts is used to check porosity, non …
Iron powder metallurgy in particular is typically performed using atomization or a reduction technique known as the sponge iron process. Atomization requires a gas, and the sponge iron process involves heating up in a kiln to produce the intermediate sponge iron, followed by crushing the material into powder.
