Abstract

The application of powder injection molding (PIM) technology for the manufacturing of metallic and nonmetallic components is of growing interes the process considerably saves time and cost. Utilizing this manufacturing method, fully dense components are being prepared in various sizes. In this work, our effort is focused on studying the densification behavior of the parts made using differently sized 316L stainless steel powders. The metal powders were mixed with an adequate amount of polymeric compounds and molded as standard tensile bars. Solvent and thermal debinding was carried out, followed by sintering in an ultra-pure hydrogen atmosphere based on the differential scanning calorimetry (DSC) cycle. Mechanical property evaluation and microstructural characterization of the sintered specimens was performed using tensile testing equipment, Vickers?s microhardness tester, and both an optical microscope (OM) and a scanning electron microscope (SEM). The results are compared and analyzed to predict the strength and weakness of the test conditions.
