- 3D Printed Chiral Cellular Solids with Amplified Auxetic Effects Due to Elevated Internal Rotation
Yunyao Jiang and Yaning Li
Version of Record online: 25 OCT 2016 | DOI: 10.1002/adem.201600609
For the first time, the concept of amplifying chirality-induced auxetic effect via elevating internal rotation efficiency is proposed and proved via multi-material 3D printing, mechanical experiments, and finite element (FE) simulations. A linear relationship between the internal rotation efficiency and the Poisson's ratio is discovered. This study provides guidelines to design new chiral cellular solids with robust auxetic effects under large deformation.
- Refining and Reinforcing Effects of In Situ AlN–TiN–TiB2/Al Composite Refiner on Aluminum

Grain refining and reinforcing effect of in situ AlN–TiN–TiB2/Al composite refiner which is prepared by nitrogen alloying based on an Al–8Ti–1B melt is much better than that of Al–5Ti–1B refiner on aluminum. That can be attributed to the miniaturization of Al3Ti, the diversification of ceramic particles and homogeneous distribution of TiB2 particles/clusters caused by nitridation.
- Dry-Sliding Wear Response of MoTaWNbV High Entropy Alloy
Anthoula Poulia, Emmanuel Georgatis, Angela Lekatou and Alexander Karantzalis
Version of Record online: 20 OCT 2016 | DOI: 10.1002/adem.201600535
The tribological performance of Mo20Ta20W20Nb20V20 Refractory High Entropy Alloy is examined for the first time, under different experimental conditions of dry-sliding testing. Various wear me-chanisms are proposed in each case. By comparing the wear response of Mo20Ta20W20Nb20V20 with that of a commercial Ni super-alloy (Inconel 718), the improved behavior of the High Entropy Alloy is highlighted in all cases.
- Development of a Transparent Scratch Resistant Coating through Direct Oxidation of Al-Coated Glass
Sayed Hadi Mousavi, Mohammad Hossein Jilavi, Marcus Koch, Eduard Arzt and Peter William de Oliveira

Scratch resistant thin films of aluminum oxide are developed through a simple and cost-effective sputtering method. The fabricated layers are composed of aluminum oxide, silicon, and silicon dioxide which play an important role in the high scratch resistance and lead to acceptable transmission. The development of protective transparent layers may find different applications in display and glass industry.
- Dual Wavelength Laser Beam Cutting of High-Performance Composite Materials
Andreas Fürst, Achim Mahrle, Dominik Hipp, Annett Klotzbach, Jan Hauptmann, Andreas Wetzig and Eckhard Beyer
Version of Record online: 19 OCT 2016 | DOI: 10.1002/adem.201600356
The remote-laser-ablation expands the area of processing strategies for fiber reinforced polymers. Laser cutting of FRP is an ambitious process because of the inhomogeneity of the reinforcement material and the polymer matrix material. The present paper shows an approach to respect this limiting factor.
