Wire Arc Additive Manufacturing (WAAM) is a manufacturing technique which uses arc as a heat source to fuse wire based on layer-by-layer cladding. In the present study, Inconel 625 alloy fabricated using WAAM has been investigated to explore its microstructure and mechanical properties, as well as the influence of heat treatment on these properties. Microstructural studies revealed variations in the microstructure across different layers of the specimen, with the bottom layer exhibiting fine primary cellular grains compared to the middle and top layers. Mechanical properties, including hardness and tensile strength, were evaluated at various temperatures from 750°C to 1200°C. The ultimate tensile strength (UTS) increased from 193 MPa to 265 MPa from the bottom layer to the top layer; however, the hardness variation with temperature was irregular. X-Ray Diffraction (XRD) tests on various heat-treated samples provided insights into the bulk metal changes due to heat treatment. Results indicate that the mechanical performance of components manufactured via WAAM is superior to those produced using other methods, making it a more economical choice for complex component manufacturing.
