Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles …

Density. Most properties of a powder metallurgy (PM) part are closely related to its final density. This density is the mass per unit volume of the part expressed in grams per cubic centimeter (g/cm³). Normally, the density of structural parts is reported on a dry, un-impregnated basis, while the density of bearings is reported on a fully oil ...
