| Abstract Scope |
Electron beam melting (EBM) of 17-4PH is yet an uncharted area, whereas this specific material is well-known in the material science for its ability to achieve required performance by an appropriate post-solidification heat treatments. The goal of this work is to perform the post process in-situ during the EBM build process.
Microstructural engineering of 3D printed precipitation hardened 17-4PH stainless steel by EBM can be achieved via two ways: fundamental beam parameter manipulation (e.g. variation of current, focus and velocity), or thermal tailoring of the entire process. These innovative approaches are unique and could be achievable with the current knowledge acquired in our group. Specifically, deep understanding of thermal processes, within and outside the bed, and metallurgical comprehension already enabled us to develop high-density (99.5%), ASTM-compliant 316L. Controlling the thermal process profile opens the ability for achieving a functionally graded material with microstructure tailored according to the designated functionality. |
