| Abstract Scope |
Additive manufacturing (AM) provides an opportunity to produce complex parts that are near net shapes, such as turbine blades, turbopumps and diffuser cases. However, a detailed investigation on mechanical behavior under varying strain rates is critical for broader applicability. Therefore, in this work, IN718 is used as a model material system to uncover the influences of post-heat treatments on the dynamic behavior of AM processed samples. Tensile and compressive quasi-static and high strain tests were performed and results were investigated depending on build orientations as well as precipitated phases. The microstructural investigation was performed on pre and post deformed samples to verify the effect of precipitated phases. Results show that mechanical behavior under varying strain rates of AM samples is very similar to those of wrought alloys with a specific heat treatment. |
