316L metal powder compaction simulation with assisted friction

摘要

Friction plays a major role in powder compaction and there is a large energy loss in trying to overcome its negative effects. It is therefore rational to use the friction to assist metal flows and reducing the amount of lubricant and its negative effects. The appropriate use of friction in practice involves the solving of complex engineering problems. The paper approach will mainly focus upon issues concerning the conversion of the friction force and simulation in PM compaction processes and improving density gradient in the powder compaction process of AISI316L austenitic powder.
