- Dynamic Behavior of Vertically Aligned Carbon Nanotube Foams With Patterned Microstructure
Ludovica Lattanzi, Ramathasan Thevamaran, Luigi De Nardo and Chiara Daraio

Micropatterned VACNT foams are fabricated to investigate the relationship between the structure and the bulk dynamic response. Changes in the patterns' geometry allow tuning the specific energy absorption of VACNTs under impact loading, and result in materials with significantly reduced bulk density. The study confirms that patterned VACNT foams hold great potential as novel lightweight material for impact protection.

Out-of-plane crushing behavior of combined aluminum honeycomb sample is investigated. Inserting processes between different honeycombs smooth the stress curve and lower the stress level, which is beneficial to the optimization design of aluminum honeycomb buffer.
- Production of Clad Steel Strips by Twin-Roll Strip Casting

Article first published online: 22 APR 2015 | DOI: 10.1002/adem.201500094
Cladding by twin-roll strip casting of a combination of the austenitic stainless steel 1.4301 and the carbon steel 1.1248 was investigated. This production method is based on the introduction of a solid strip between the casting rolls, where the joining takes place. For the first time this process is used to combine two steel alloys. Shear tests with an optimized shearing surface are used to measure the mechanical resistance of the clad joint.
- Synthesis and Characterization of TiAl-Based Nanocomposites by a Melt Electromagnetic Stirring Process
Zhiyong Zhang, Yanli Wang, Xiangjun Xu, Yongfeng Liang, Laiqi Zhang and Junpin Lin
Article first published online: 21 APR 2015 | DOI: 10.1002/adem.201400557
γ-TiAl-based nanocomposites have been synthesized by an electromagnetic stirring process; finely dispersed nanoparticles are obtained with the aid of reactive wetting; the wettability of the studied nanoparticles are sorted in descending order as TiO2 > TiC > Al2O3 > Y2O3, and TiAl/TiC nanocomposite has a high microhardness of 450 HV. Effects of the nanoparticles on solidification process and the cast microstructures are discussed.
- High Strength and Electrical Conductivity of Al-Fe Alloys Produced by Synergistic Combination of High-Pressure Torsion and Aging
Jorge M. Cubero-Sesin, Makoto Arita and Zenji Horita
Article first published online: 21 APR 2015 | DOI: 10.1002/adem.201500103
High pressure torsion (HPT) processing and aging was applied to Al-Fe alloys with different initial states. An adimensional figure of merit is proposed to ponder both the strength and electrical conductivity. The figure of merit is plotted with respect to the strain imposed by HPT, showing the superior properties of Al-2%Fe, particularly after peak-aging (0.5 h) which shows recovery of electrical conductivity from precipitation of nano-sized Fe-rich particles.
