Laser and Arc Additive Manufacturing of Stainless Steels and Nickel Superalloys
This community investigates the fabrication of metallic components using laser and arc-based additive manufacturing, focusing on how processing parameters influence the microstructure and mechanical performance of stainless steels and nickel-based superalloys.
The research centers on laser powder bed fusion, wire arc additive manufacturing, and laser cladding. Recurring materials include 316L stainless steel, Inconel 718, and other nickel-based superalloys. The work examines melt pool dynamics, energy deposition, and residual stress to understand microstructural evolution. Key topics include grain structure control, defect formation, and heat treatment optimization to achieve specific mechanical properties. Applications cited in titles include gas turbine components, aerospace heat exchangers, and corrosion-resistant structural parts.
The largest share of the community's output is found in nickel research, accounting for 4.4% of all nickel research, with 9,015 papers in this group. Tungsten and aluminium also appear frequently, representing 2.1% and 1.7% of their respective element research.
The community comprises 54,631 papers, primarily published in Materials Science and Engineering A, Journal of Materials Research and Technology, and Journal of Alloys and Compounds.
Recent work continues to focus on optimizing microstructures in nickel-based superalloys and stainless steels. Specific studies address single-crystal-like alloy fabrication, stress corrosion resistance in austenitic stainless steels, and the mechanical properties of alloys produced via directed energy deposition versus powder bed fusion.
