Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

open access: yesAdvanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Effect of Annealing Temperature on Microstructure and Dry‐Sliding Behavior of Powder Bed Fusion–Laser Beam Ti6Al2Sn4Zr6Mo Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Improved Strength and Corrosion Resistance of Ti–50Zr Alloy Through Heat Treatment

open access: yesAdvanced Engineering Materials, EarlyView.
This work systematically analyzes the effects of heat treatment on mechanical properties and corrosion behavior of Ti‐50Zr alloy produced via vacuum arc melting. Microstructure transforms from coarse lamellar α phase in as‐cast condition to fine and uniformly distributes acicular α′ phase in heat‐treatment state.
