Laser and Arc Additive Manufacturing of Stainless, Titanium, and Nickel Alloys
This community focuses on the fabrication of metallic components using laser and arc-based additive manufacturing, specifically analyzing the resulting microstructures, mechanical properties, and defect formation in stainless steels, titanium alloys, and nickel-based superalloys.
The work centers on laser powder bed fusion, directed energy deposition, and wire arc additive manufacturing. Recurring subjects include 316L and duplex stainless steels, Ti-6Al-4V, and Inconel 718. Researchers examine how process parameters like energy deposition and heat treatment influence grain structure, residual stress, and corrosion resistance. The literature also covers laser cladding and welding, as well as the design of lattice structures and metamaterials. These studies aim to optimize the relationship between processing conditions, microstructural evolution, and final component performance for structural and aerospace applications.
The community is most prominent in research involving Tungsten, where it accounts for 3.8% of all tracked papers, and Argon, representing 2.5% of that element’s research. It also constitutes 2.1% of Titanium research, with 6,197 papers in this group.
The community comprises 51,332 papers, with the highest publication volumes found in Optics & Laser Technology, the Journal of Materials Research and Technology, and The International Journal of Advanced Manufacturing Technology.
Recent work continues to explore the microstructural evolution of nickel superalloys and stainless steels, with specific attention to stress corrosion cracking in duplex alloys and the fabrication of single-crystal-like structures.
