| Abstract Scope |
Additive manufacturing (AM) has shown improvement in terms of affordability, sustainability, waste reduction and energy saving. In this study, laser-based direct energy deposition was used at Premier Technology Inc. to build austenitic 316L stainless steel parts with specific geometries for various applications. Wires of austenitic 316L stainless steel were utilized to build the parts under argon gas environment. Density was measured following Archimedean principle, microhardness was measured using Vickers microhardness testing, and strength and ductility properties were evaluated via tensile testing. Nanohardness and modulus mapping were performed using nanoindentation technique to obtain localized gradient in mechanical properties. Microstructure was characterized using optical and scanning/transmission electron microscopy to correlate the obtained mechanical properties to the observed microstructure. The obtained mechanical properties are found to be comparable to those of conventionally manufactured 316L. The research is supported by the Idaho Global Entrepreneurial Mission (IGEM) Program of the Idaho Department of Commerce. |
