Microstructure and Non-Metallic Inclusions in 316L Steel for Net Shape Manufacturing

摘要：

　　Austenitic 316L stainless steel is a relevant alloy for use in Net Shape and Additive Manufacturing(NSAM)technologies for many different industrial applications.It can be powder processed using Metal Injection Moulding(MIM),Additive Manufacturing(AM)and Hot Isostatic Pressing(HIP).This work reports the grain boundary characterization(in particular proportions of both Σ3 and Σ9)and grain size in austenitic 316L stainless steel after HIP product fabrication from gas-atomised powder precursors following either air melting(sieved to < 150 μm)or vacuum induction melting(sieved to 106-150 μm).A comparison of the non-metallic inclusions in the HIP products has also been made.
