AbstractIn this article, the corrosion behavior of stainless steel 316L in a low melting point novel LiNO3-NaNO3-KNO3-NaNO2 eutectic salt mixture was investigated at 695 K which is considered as thermally stable temperature using electrochemical and isothermal dipping methods. The passive region in the anodic polarization curve indicates the formation of protective oxides layer on the sample surface. After isothermal dipping corrosion experiments, samples were analyzed using SEM and XRD to determine the topography, corrosion products, and scale growth mechanisms. It was found that after long-term immersion in the LiNO3-NaNO3-KNO3-NaNO2 molten salt, LiFeO2, LiFe5O8, Fe3O4, (Fe, Cr)3O4 and (Fe, Ni)3O4 oxides were formed. Among these corrosion products, LiFeO2 formed a dense and protective layer which prevents the SS 316L from severe corrosion.

The effects of various Nickel and Nickel with Cobalt additions in P/M 316L stainless steel on sigma phase and oxide formations were investigated. Various powder mixtures of P/M316L with Ni and both Ni + Co powders as 1, 2, 3 and 4% by wt.%, were compacted using single action press under 498 MPa and sintered at 1300 °C for 30 minutes in hydrogen atmosphere. Then specimens were exposed at temperature of 800 °C and 900 °C for 25, 50, 75 and 100 hours in order to investigate the microstructural stability. It was found that specimens with both Co and Ni additions could reduce amount of sigma phase formation especially at heating of 900 °C. After all heat treatments, oxide scales had grown in closed pores during heating, therefore, the amount and size of internal porosity were decreased. It was also observed that the amount and size of porosity of heated specimens still have the same tendency as sintered specimens. The oxide scale in the matrix is mainly composed of Fe3O4 and Cr2O3 in the closed pores.

AbstractAdditive manufacturing (AM), and in particular selective laser melting (SLM) technology, allows to produce structural components made of lattice structures. These kinds of structures have received a lot of research attention over recent years due to their capacity to generate easy-to-manufacture and lightweight components with enhanced mechanical properties. Despite a large amount of work available in the literature, the prediction of the mechanical behavior of lattice structures is still an open issue for researchers. Numerical simulations can help to better understand the mechanical behavior of such a kind of structure without undergoing long and expensive experimental campaigns. In this work, we compare numerical and experimental results of a uniaxial tensile test for stainless steel 316L octet-truss lattice specimen. Numerical simulations are based on both the nominal as-designed geometry and the as-build geometry obtained through the analysis of µ-CT images. We find that the use of the as-build geometry is fundamental for an accurate prediction of the mechanical behavior of lattice structures.
