Electrospark‐Deposited AlCrFeCoNi High‐Entropy Alloy Coatings on Steel: Microstructure Evolution, Mechanical Properties, and Corrosion Response

open access: yesAdvanced Engineering Materials, EarlyView.
AlCrFeCoNi high entropy alloy coating is applied on steel using electrospark deposition. The microstructure evolution and phase transformation of the as‐deposited and heat‐treated coatings is characterized and discussed. Reduced microhardness and yield strength are measured after heat treatment.

Micromechanical Characterization of 316L‐V4E Steel Transitions Produced by Electron Beam Powder Bed Fusion with Dual‐Hopper Alternating Layer Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
This work applies High‐Speed Nanoindentation to study multi‐material transitions in powder bed fusion–electron beam melting components. The aim is to assess the mechanical gradients and interfacial behavior between American iron and steel institute 316L stainless steel and V4E tool steel in additively manufactured structures.

Fabrication‐Directed Entanglement for Designing Chiral and Anisotropic Metamaterial Foams

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces fabrication‐directed entanglement (FDE), combining viscous thread printing and topology optimization to program entangled foams with spatially patterned stiffness. By tuning coil density, FDE enables anisotropy, programmable Poisson's ratio, and chirality in foams.
