Abstract Scope |
Stainless-Steel 316L (SS316L) and Inconel 718 (IN718) both are FCC alloys having the same preferred solidification orientation along the cellular solidification structures that form during rapid solidification. Despite these, their reported texture along build direction generally differs: SS316L develops <110> while IN718 develops <100>. We study the thermal history and solidification microstructure development in laser bed powder fusion through systematic experimentation supported by finite element thermal modeling. These FCC alloy systems were directly compared under various processing and solidification to determine the fundamental differences and similarities in cellular solidification. We further showed how the growth of cellular structures can be controlled to tailor the preferred texture along the build direction of SS316L & IN718 as a function of process parameters. |
