N2 - While residual porosity sealing by well-established post-sinter processing including either copper infiltration or stream treatment or organic resin vacuum impregnation results in certain enhancement in functional performance and mechanical properties of artifacts from powder metal (PM) steels, neither one of referenced above processing steps ensures comprehensive solution from economic and/or structural standpoint. With this regard, newly developed hybrid processing comprising partial copper infiltration with subsequent partial vacuum impregnation by inorganic compounds provides viable alternative for cost-efficient enhancement of mechanical characteristics and microstructure of artifacts from PM steels. Obtained data on effect of aforementioned hybrid post-processing of artifacts from several PM steels are presented and discussed.
