- Compression Behavior of Ti Foams with Spherical and Polyhedral Pores
Krzysztof Pałka, Grzegorz Adamek and Jarosław Jakubowicz
Version of Record online: 27 MAY 2016 | DOI: 10.1002/adem.201600169
The paper investigates the formation, morphology, and mechanical behavior under compression load of Ti foams. Metal foams (70% porosity) are made with spherical and polyhedral voids (pores), respectively. Foams are tested by interrupted compression during μCT scan.
- The TiC/Ni–Cr Composites with Low Thermal Expansion and Electrical Resistivity Applied for IT-SOFC Interconnects
Qian Qi, Yan Liu, Hui Zhang, Jing Zhao, Linlin Gai and Zhengren Huang
Version of Record online: 25 MAY 2016 | DOI: 10.1002/adem.201600190
TiC/Ni-Cr composites are promising candidates for IT-SOFC interconnects. The contiguity of TiC plays a crucial role on the CTE and electrical resistivity of composites. The partial in situ method and isothermal heat treatment significantly decrease the CTE and electrical resistivity of TiC/Ni–Cr composites by increasing the contiguity of TiC.
- Slot-Die-Coated V2O5 as Hole Transport Layer for Flexible Organic Solar Cells and Optoelectronic Devices
Michail J. Beliatis, Martin Helgesen, Rafael García-Valverde, Michael Corazza, Bérenger Roth, Jon E. Carlé, Mikkel Jørgensen, Frederik C. Krebs and Suren A. Gevorgyan
Version of Record online: 23 MAY 2016 | DOI: 10.1002/adem.201600119
V2O5 is optimized as a hole transport layer in roll-coated organic solar cells and photodetectors and is tested for stability. As a demonstrator, a proximity sensor is constructed based on an organic detector and a light-emitting diode mounted on 3D-printed scaffold. The work highlights the potential of organic solar cells and photodetectors as cost-efficient emerging technologies.
- Bone-Inspired Materials by Design: Toughness Amplification Observed Using 3D Printing and Testing
Flavia Libonati, Grace X. Gu, Zhao Qin, Laura Vergani and Markus J. Buehler
Version of Record online: 23 MAY 2016 | DOI: 10.1002/adem.201600143
Nature uses few universal building blocks to achieve multi-functionality and amplification of mechanical properties through different hierarchical structures. With a similar approach, it is possible to use pure polymers as building blocks to investigate, through bio-inspired design and 3D printing, the effect of different geometrical features.
- Friction and Heat Transfer Coefficient Determination of Titanium Alloys during Hot Forging Conditions
Ritanjali Sethy, Lander Galdos, Joseba Mendiguren and Eneko Sáenz de Argandoña
Version of Record online: 20 MAY 2016 | DOI: 10.1002/adem.201600060
The friction factor of Ti–6Al–4V titanium alloy under hot forging situation has been determined taking into account the influence of the HTC in the ring tests. For this reason, the combined approach of columnar upsetting thermal tests (HTC test) and ring-compression tests of as-received specimens with and without glass coatings with FE simulation have been performed in this paper.
