SIMULATION OF INFLUENCE OF FRICTION FORCES IN METAL POWDERS COMPACTION PROCESS OF STAINLESS STEEL 316L

摘要

The purpose of this study is to simulate powder compaction process with active friction forces, and what is the impact of friction forces to increase densification in compaction process. The process is intended to be used in the compaction of hard deformable materials, which increased to approximately 90% densification required very high compaction pressures. These pressures are high, significant wear of the tools produce the compaction and thereby increasing production costs of finished parts from metal powders.
