Additive Manufacturing of Structural Alloys and Their Mechanical Properties
This community investigates how metals are built layer-by-layer using lasers and arcs, and how the resulting internal structure determines their strength, durability, and resistance to corrosion.
The work centers on stainless steels, titanium alloys, nickel-based superalloys, and aluminum alloys processed via laser powder bed fusion, wire arc additive manufacturing, and laser cladding. Researchers focus on controlling microstructure evolution, grain boundaries, and heat treatment to manage mechanical behavior, fatigue resistance, and corrosion performance. Specific attention is paid to hydrogen embrittlement in steels and the optimization of melt pool dynamics to reduce defects. The applications span aerospace turbine components, biomedical implants, and structural parts requiring high strength-to-weight ratios.
The largest share of the community's output is found in titanium research, representing 13.9% of all titanium research, with 8,528 papers in this group. Nickel and chromium also contribute significantly, accounting for 10.2% and 7.4% of their respective element research.
The community comprises 58,106 papers, published primarily in Materials Science and Engineering: A, Journal of Materials Research and Technology, and Metals.
Recent work continues to refine the microstructural control of nickel-based superalloys for turbine disks and the corrosion resistance of austenitic stainless steels in high-temperature water, alongside studies on high-strength titanium alloys for load-bearing applications.
