Additive manufacturing of interstitial-strengthened high entropy alloy: Scanning strategy dependent anisotropic mechanical properties

Wei Zhang et al.

Summary: A non-equiatomic interstitial-strengthened high entropy alloy (iHEA), Fe49.5Mn30Co10Cr10C0.5 (at.%), is manufactured by laser powder-bed fusion (LPBF) with stripe and chessboard scanning strategies. The relationship between laser scanning strategies and resulting microstructure, textures, and anisotropic mechanical properties in as-built iHEA is investigated. Results show that LPBF processed iHEA exhibits excellent strength-ductility synergy due to combined deformation mechanisms. The mechanical anisotropy is more evident in samples printed by the stripe scanning strategy compared to the chessboard-scanned samples, attributed to heterogeneous grain morphology and crystallographic texture resulting from different scanning strategies.

Design, microstructure, and mechanical property of negative Poisson's ratio porous structure fabricated by LPBF of AlCoCrFeNi2.1 eutectic high-entropy-alloy

Xiangfei Peng et al.

Summary: Negative Poisson's ratio (NPR) materials deform in an atypical manner. By utilizing a high-yield strength and high ductility eutectic high-entropy alloy (EHEA) fabricated through laser powder bed fusion (LPBF), the mechanical properties and NPR behavior of structures are enhanced. Static and dynamic compression experiments show that the nano-scale cellular eutectic microstructure effectively restricts dislocation movement, leading to improved strength, toughness, and mechanical energy absorption.

Hierarchically heterogeneous microstructure enables ultrahigh-strength and good ductility in selective laser melted eutectic high-entropy alloys

Zhenghong Fu et al.

Summary: This study reports the development of a selectively laser melted eutectic high-entropy alloy with ultrahigh strength and good ductility through tuning micro-to nano-scale heterogeneous microstructures. The nano-sized B2 and L12 phases effectively hinder dislocation motion and improve strength, while the face-centered cubic matrix ensures uniform deformation and the Cr-rich clusters alleviate possible brittle failure of the hard B2 phase.

Ultrahigh-strength and ductile CoCrFeNi-based high-entropy alloys manufactured by laser powder bed fusion with multiple strengthening mechanisms

Zhining Wu et al.

Summary: In this study, CoCrFeNi-based alloy with the addition of B4C micro-particles was manufactured using L-PBF. Nanosized precipitates consisting of boride and varying carbides were found in the form of a core-shell structure, with an in-site transformation of carbides occurring during manufacturing. Compared to the matrix, CoCrFeNi-B4C alloy exhibited higher tensile yield and ultimate strength, as well as competitive ductility. The exceptional mechanical properties can be attributed to precipitate hardening, dislocation hardening, grain refinement, and particle-dislocation interaction.
