Abstract Scope |
We will present an analysis of the sizes, morphologies, and 3D distributions present within laser-powder bed fusion additively manufactured builds of 316L stainless steel. Porosity is a ubiquitous characteristic of structures built by additive manufacturing, and the amount and distribution of that porosity can have detrimental impacts on the performance of such materials. We will discuss the different morphologies and sizes of porosity in the build, the increased density of pores that form in the near-surface regions, and observed variations in porosity along the build direction, as well as the origins of these characteristics. In addition, we will discuss the impact that porosity can have on the mechanical and corrosion performance of L-PBF additively manufactured 316L stainless steel. |
