Trans. Nonferrous Met. Soc. China 24(2014) 3732-3738 Capping effect of reducing agents and surfactants in synthesizing silver nanoplates Yang YAN, Ke-bin CHEN, Hao-ran LI, Wei HONG, Xiao-bin HU, Zhou XU State Key Laboratory of Metal Matrix Composites, Shanghai Jiao Tong University, Shanghai 200240, China Received 16 December 2013; accepted 12 September 2014 Abstract: The effect of reducing agents......
of Springer Nature 2020 Abstract: We have established an elastoplastic analysis model to explore the effect of loading path in an incompressible thin-walled tube under the combined action of axial..., and the plastic stress-strain relationship of twelve stress paths in different stress areas is derived. The "primary effect" of the stress path on plastic strain is demonstrated, namely, the plastic strain......
: The macro scale fabrication of high performance metals with nano-structure and nano effect and the revelation of the characteristic of microstructure evolution to the functional regulation are the major... for the applications were proposed. Key words: metal nano-materials; composites; interface; size effect 金属材料的力学性质和物理性质在很大程度上依赖于其组织的特征尺度,典型的特征尺度是晶粒尺寸.通常情况下,对于纯金属和单相固溶体合金,传统的Hall-Petch关系σy=σ0+Ad-1/2(其中σy是屈服强度......
and the electrodeposited pure Ni coating were comparatively investigated in order to elucidate the effect of CeO2 at different temperatures and also CeO2 contents on the oxidation behaviour of Ni-CeO2...; nanocomposite coating; oxidation; reactive-element effect 1 Introduction The composite electrodeposition technique is a low-cost and low-temperature method suitable for producing metal matrix composite......
J. Cent. South Univ. (2019) 26: 1807-1819 DOI: https://doi.org/10.1007/s11771-019-4135-2 Stress-drop effect on brittleness evaluation of rock materials SHI Gui-cai(史贵才)1, CHEN Guan(陈冠)2, PAN Yu-tao... and the development process of rock fracture. Extensive literature review has been conducted on this issue; meanwhile, experimental and numerical studies have been conducted on the stress-drop effect......
comparatively investigated, with the emphasis on the effect of Y2O3. SEM/EDAX and TEM characterizations showed that the dispersion of Y2O3 refines the grains. Oxidation at 900 ℃ for 100 h showed that the addition of Y2O3 significantly improved the cyclic oxidation resistance of Ni3Al coating. The effect of Y2O3 on the microstructure and the oxidation of the Ni3Al coating were discussed in detail......
Analysis on aerodynamic effect of high-speed train passing tunnel with lining structures LIU Feng, YAO Song, YANG Mingzhi, ZHANG Jie (Key Laboratory of Traffic Safety on Track of Ministry of Education... no significant effect on the aerodynamic effects of existing double-line tunnel, and the difference in maximum pressure values of measuring points is below 2%. Thus, the lining technology is proposed......
