Role of Si-decorated cell structure in cryogenic tensile behavior of additively manufactured AlSi10Mg alloy

Haeum Park, Jisung Yoo, Hyojin Hwang, Minsoo Jin et autres

Laser powder bed fusion (LPBF)-fabricated AlSi10Mg alloy exhibits markedly increased strain hardening at cryogenic temperatures because Si-assisted cell heterogeneity intensifies the accumulation of geometrically necessary dislocations and produces a strong hetero deformation induced hardening effect. However, coarse cells along melt pool boundaries …

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 …
