Abstract Scope |
The objective of this paper is to investigate the material properties of 17-4PH stainless steel printed by the Atomic Diffusion Additive manufacturing technique. Samples with film cooling holes, different orientations were manufactured in a Markforged Metal-X machine. The presence of cooling in these samples helps to understand printability and accuracy of internal cooling holes, as manufactured by Metal-X machine. Manufactured samples were washed to remove the plastic binder. These pre-sintered samples were tested, before sintering, for density, microstructure analysis, CT scan, roughness, XRF to understand the material properties. Printed holes and their anomalies, selection of standards of testing will be discussed along with the material behavior of 17-4PH stainless steel. |
