Solidification microstructure and elemental segregation in laser-based powder bed fusion additively manufactured IN738LC Ni-based superalloy

Shailendra Kumar Verma, Soung Yeoul Ahn, Sushil Kumar, Gaon Yu et autres

• The solidification microstructure in AM IN738LC Ni-based superalloy is investigated. • High laser power and high scan speed give the minimum defects in the as-built superalloy. • Dendrite impingement decreases undercooling, thereby lowering solute segregation. • The high laser power condition …

Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

Min Young Sung, Tae Jin Jang, Sang Yoon Song, Junho Lee et autres

Abstract Metallic materials for aerospace and liquid hydrogen technologies need to maintain high strength and ductility under cryogenic conditions. However, conventional strengthening strategies typically increase defect density and promote strain localization, resulting in a strength–ductility trade‐off. This limitation becomes more critical at …

Influence of Zn/Mg ratio on cathodic corrosion and hydrogen embrittlement in crossover Al-Zn-Mg alloys

Dae Cheol Yang, Chang Gi Lee, Sang Yoon Song, Hyein Lee et autres

Crossover Al-Zn-Mg alloys combine the strength of both 5xxx and 7xxx Al alloys, offering a desirable combination of strength, ductility, and recyclability. The exceptional performance of these alloys is primarily due to the coexistence of η′ and T′ phases; however, an influence …
