- 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.

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.

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.
- Fatigue-Crack-Growth Behavior of Two Pipeline Steels

The fatigue-crack growth behavior of two pipeline steels, Alloy B [Fe–0.05C–1.52Mn–0.12Si–0.092Nb, weight percent (wt%)] and Alloy C [(Fe–0.04C–1.61Mn–0.14Si–0.096Nb, wt%)], is studied. Alloy B demonstrates a better fatigue resistance than Alloy C under various conditions [stress ratios (R) of 0.1 and 0.5, testing frequencies (f) of 10, 1, and 0.1 Hz]. As shown in the figure below, when R = 0.5 and f = 1 Hz, it can be clearly seen that the fatigue-crack-growth rate (FCGR) of Alloy C is greater than that of Alloy B under all ΔK values. Possible reasons are proposed to explain the phenomenon.
- Bioinspired Multifunctional Ceramic Platelet-Reinforced Piezoelectric Polymer Composite
Zhe Xu, Julia Bykova, Mahmoud Baniasadi, Salvador Morenor, Zhong Zhou, Nandita Das, Sasaank Bandi, Yang Xi, Dong Qian, Ray H. Baughman and Majid Minary-Jolandan
Version of Record online: 17 OCT 2016 | DOI: 10.1002/adem.201600570
Bioinspired multifunctional composite of single crystal ceramic platelets and piezoelectric polymer prepared by layer-by-layer approach. The composite is transparent, is piezoelectric, and shows large ductility. Effect of annealing process on the morphology of the polymer phase and on the mechanical properties of the composite is also investigated.
