Mono- and binary silicides Mo–Nb–Si with different ratios of Nb/Mo are synthesized from the highly exothermic mixtures of MoO3, Nb2O5, Si, and Al by the method of SHS-metallurgy.
- Preparation and Mechanical Properties of (Ni–Fe)–Graphene Composite Coating
Lan Zhang, Na Li, Huimin Xia, Jingyi Zhang, Pingping Zhang, Miting Xu and Huizhong Ma

(Ni–Fe)–Graphene composite coatings are prepared on the stainless steel substrate by electro-deposition technique. The Graphene Nano-platelets wrapped by Ni–Fe crystalline grains are embedded into the coating layer and substrate coated with composites exhibits maximum threefold enhancement in hardness and 14.9% improvement in elastic modulus, which are attributed to the unique structure and prominent mechanical property of graphene.
- Identification of the Norton-Green Compaction Model for the Prediction of the Ti–6Al–4V Densification During the Spark Plasma Sintering Process
Charles Manière, Ugras Kus, Lise Durand, Ronan Mainguy, Julitte Huez, Denis Delagnes and Claude Estournès
Version of Record online: 22 AUG 2016 | DOI: 10.1002/adem.201600348
An in situ SPS identification, using a complete and non-reductive method, of the Norton-Green law is performed on a Ti–6Al–4V materials. The identified model is tested on two independent SPS experiments for the densification of this powder material and shows very good prediction of the experimental sintering trajectory.
- In Situ Curing and Out-of-Autoclave of Interply Carbon Fiber/Carbon Nanotube Buckypaper Hybrid Composites Using Electrical Current
Nam Nguyen, Ayou Hao, Jin Gyu Park and Richard Liang
Version of Record online: 19 AUG 2016 | DOI: 10.1002/adem.201600307
Hybrid composite including carbon nanotube sheets and carbon fiber prepregs is in situ cured by applying electrical current to carbon nanotube layers. The relationship between input current and composite temperature is explored. Fully cured samples show low void content and good storage modulus. In situ curing is demonstrated as energy saving technique to fabricate multifunctional composite.
- Enhanced Grain Refinement and Porosity Control of the Polycrystalline Superalloy by a Modified Thermally Controlled Solidification
Ziqi Jie, Jun Zhang, Taiwen Huang, Haijun Su, Yafeng Li, Lin Liu, Wenchao Yang and Hengzhi Fu
Version of Record online: 17 AUG 2016 | DOI: 10.1002/adem.201600320
A technique combined a modified thermally controlled solidification process (MTCS) with mixed refiner is designed to enhance grain refinement and restrain porosity in polycrystalline superalloy castings. In comparison to the conventional casting process (CC), the technique significantly refines grain size, almost eliminates porosities, and dramatically improves the mechanical properties.
