| Abstract: | Warm flow compaction is a novel,net-shape forming process that can produce complex powder metallurgy parts.It combines the advantages of warm compaction and metal injection molding techniques.Regular 17-4P stainless steel powders were used in warm flow compaction to fabricate cross-shaped parts.Dewaxing process,forming process,microstructures,hardness and density of the sintered part were investigated.Results show that binder-treated warm compaction method can produce complex-shaped components with high mec... |
