It is well known that the properties of powder metal components increase as the density increases. There are many methods of increasing the density of green compacts, including lubricants, warm compaction and increased compaction pressures. The purpose of this paper will be to describe the properties achievable using elevated die and/or powder temperature to achieve increased green densities. Green densities achieved using elevated temperature processing will be compared to green.
