| Abstract Scope |
The microstructural and mechanical responses of wire-arc additively manufactured (WAAM) 410NiMo ferritic-martensitic stainless steel (ER410NiMo, AWS-5.9) to various print conditions have been systematically investigated. 410NiMo was selected as a model case of “highly-alloyed”, “phase transformation-involved” ferrous alloys which could be a basis of various Fe-base materials of interest for industrial use, such as precipitation-hardening steels or tool steels. By considering a complicated shape component production through WAAM, multiple walls were printed with three different inter-pass temperatures (150, 300, and 500°C) and wall thicknesses (2-, 4-, and 8-beads), which were subjected to cross-sectional microstructure characterization with 2D hardness measurement, defect distribution analysis by high-energy x-ray tomography, and tensile/fatigue property evaluation. The results indicated that low inter-pass temperature combining with large wall thickness would result in a variation of mechanical properties attributed to inhomogeneous microstructure evolution as well as internal defect/inclusion formation. Detailed correlation with the process parameters will be further discussed. |
