  • The influence of MIM and sintering-process parameters on the mechanical properties of 316L SS
    Berginc, Boštjan ; Kampuš, Zlatko ; Šuštaršič, Borivoj
    Metal injection moulding (MIM) is a relatively new and promising technology for the mass production of small, complex near-net-shape products. The dimensions, tolerances and mechanical properties of ... MIM products are influenced by the process parameters of injection moulding, as well as by the sintering. The mechanical properties primarily depend on the sintering density and microstructure. However, the process parameters of the injection moulding must not be neglected. This investigation showed that the appropriate mechanical properties of MIM products can be obtained. However, they are drastically reduced if inappropriate injection moulding and sintering conditions are selected. An incomplete debinding process results in residual carbon, which hinders the sintering. High-temperature vacuum sintering causes the evaporation of volatile elements (chromium, manganese), resulting in an increased near-surface porosity. The formation of a hard and brittle sigma phase is controlled by the cooling rate after sintering. The ceramic supports can react with the sintered steel. In this paper the influence of injection-moulding and sintering parameters on the mechanical properties of sintered material is presented and discussed.
