In conventional warm compaction, both powder and die are heated to a certain temperature during

compaction. This is a technique for producing P/M compacts with higher green and sintered strength as

compared to room temperature pressing...

Addition of lubricant in the form of admixed with powder reduces friction between die wall and powder during compaction of P/M parts. However, it has detrimental effect on mechanical properties. On the other hand, warm compaction of powders improves...
