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

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

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.

We grow and characterize novel composite films of TiN/Tapering/NbN/Tapering/TiN on c-cut sapphire substrate. The tapering layer is a gradual transition between TiN and NbN so that no distinct interface exists. A micro-strip resonator is fabricated and its intrinsic quality factors from the composite film under 16 mK is over 9 000 at 0 field and 5 300 under 100 mK at 0.35 T. The resonators are designed to support electron spin resonance for sensing and quantum information processing.
- Preparation and Interface Investigation of Fe/Al2O3P Composite Activated by Ni and Ti
Shuli Tang, Yimin Gao, Yefei Li and Qiaoling Zheng

Ceramic particles preforms are synthesized by vacuum sintering reaction between Al2O3 particles and Ni–Ti complex powders. Then the Cr15 matrix composite is fabricated by infiltration casting process. The preforms sintered by Al2O3 and Ni–Ti have high compressive strength, and the three-body abrasive wear resistance of composite is over 12 times higher than Cr15.
