Effect of Si Content on Sintering Behavior of Zr Pre-alloyed 316L Stainless Steel Powder

Effect of Zr, Nb and Ti Additions on Injection Molded 316L Stainless Steel: Microstructural, Mechanical Properties and Corrosion Resistance

“…As a result of this, it may be possible high performance for final sintered parts. Earlier investigations on injected molded 316L stainless steel focused on the effect of powder characteristics, the development of a binder system and debinding properties, sintering conditions, residual carbon and oxygen content on microstructure and small additives such as Zr, Ti and B to enhance sintering behavior and mechanical properties [5][6][7][8] The present work investigates the effect of Zr, Nb and Ti additions microstructural and mechanical properties of injection molded 316L stainless steels. Metallographic techniques were employed for the sintered tensile bars to investigate the microstructural development.…”

“…316L alloys in stainless steel family have an average density, relatively high strength and excellent corrosion resistance in many media [4]. These materials can be easily produced by conventional powder metallurgy processing, but a major problem to be overcome in the conventional powder processing is the oxide film and residual radical elements such as C, O and N [5]. Oxides, nitrides and sulfur on surfaces of powder prevents to high densification at sintering stages.…”
