Additive Manufacturing and Corrosion Behavior of Stainless Steel, Titanium, and Nickel Alloys
This research community investigates the microstructural evolution, mechanical performance, and environmental durability of metallic alloys, with a primary focus on stainless steels, titanium, and nickel-based systems. The work addresses how these materials behave under stress and corrosion, and how their properties can be optimized through advanced manufacturing techniques like additive manufacturing and heat treatment.
The community’s work centers on the interplay between processing methods and material outcomes. Recurring themes include the effects of laser powder bed fusion, selective laser melting, and wire arc additive manufacturing on the microstructure of austenitic stainless steels (particularly 316L) and duplex stainless steels. A significant portion of the research examines corrosion resistance, hydrogen embrittlement, and fatigue behavior in these alloys. The studies frequently analyze how heat treatment and energy deposition during manufacturing influence grain boundaries and phase transformations. The materials discussed are predominantly structural alloys used in demanding environments, where the balance between strength, ductility, and resistance to chemical degradation is critical.
The largest share of the community's output is found in titanium research, accounting for 15.5% of all titanium research tracked, with 18,262 papers in this group. This is followed by nickel, which contributes 8.6% of its research field (8,444 papers), and chromium, which accounts for 7.8% of its field (3,899 papers).
The community comprises 122,909 papers, published most frequently in Materials Science and Engineering: A, Corrosion Science, and Metals.
Recent work continues to focus on optimizing the corrosion resistance of precipitation-hardened stainless steels for high-temperature water environments and developing single-crystal-like nickel superalloys via laser powder bed fusion. Other recent studies examine the microstructure of copper-based alloys deposited via cold metal transfer and the design of additively manufactured metallic lattice structures for multifunctional applications.
