Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

Advanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

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

Advanced 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

Advanced 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

A Novel Simplified Approach to Physically Simulate Wire‐Arc Directed Energy Deposition Conditions

Advanced Engineering Materials, EarlyView.
Scarcity of specialized titanium alloy wires and high experimental wire production costs impedes wire‐arc directed energy deposition (waDED) adoption in industry. A novel, wireless approach is introduced to accelerate and economize titanium alloy development.

3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

Advanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.
