| Abstract Scope |
A transformative hybrid solid-state additive manufacturing process, Additive Friction Stir Deposition (AFS-Deposition) provides a new path to either fabricate or repair components for wrought performance. In this work, the fatigue behavior of AFS-Deposition manufactured Inconel 625 is characterized and modeled. The AFS-Deposition method is a unique solid-state manufacturing process that differs from traditional friction stir welding since solid rod is fed through a non-consumable rotating cylindrical tool generating heat and plastically deforming the feedstock material through controlled pressure as successive layers are built upon a substrate. In order to quantify the fatigue behavior of the AFS-Deposition Inconel 625, strain-life experiments were conducted under low and high cycle conditions. The cyclic behavior of this alloy displayed varying degrees of cyclic hardening depending on the strain amplitude. However, AFS-Deposition Inconel 625 appeared to exhibit generally superior fatigue performance compared to the wrought Inconel 625. |
