temperatures 图5 样品熔体层与直径5 mm的ZT3块体非晶的XRD谱 Fig. 5 XRD patterns of molten layer and ZT3 bulk metallic glasses with diameter of 5 mm 对不同液桥样品熔体层中的枝晶相和非晶相进行成分分析发现,不同保温温度的液桥样品中析出的枝晶相成分基本一致,与基片的成分接近... in different parts of molten layer 图7 液桥样品背散射图像 Fig. 7 Back scattered micrograph of samples at different temperatures 4 结论 1) 在液桥实验中,基片发生溶解,随着保温温度的升高,基片的溶解深度逐渐增大.下基片界面处由于受到重力驱动对流的作用,其溶解量大于上基片......
institutes and universities [5–10]. However, overall success of the inert anode technology is based on the systematical breakthrough in inert material, new cell design and new electrolysis process. Practically, bubbles generated in the electrolysis process are one of the key factors for new cell structure design and for electrolysis process operation since the bubble motion and the electrolyte......
NiPS3 quantum sheets modified nitrogen-doped mesoporous carbon with boosted bifunctional oxygen electrocatalytic performanceKai Huang1,Yuyang Xu1,Yanpeng Song2,3,Ruyue Wang1,4,Hehe Wei4,Yuanzheng Long4,Ming Lei1,Haolin Tang5,Jiangang Guo3,Hui Wu41. State Key Laboratory of Information Photonics and O......
composite reinforced by γ-Al2O3 particles was produced by adding NH4AlO(OH)HCO3(AACH) into molten Al-Si alloy at 850 ℃. During stirring γ-Al2O3 particles are formed by the decomposing reaction of AACH... Al-Si alloy matrix composites reinforced by γ-Al2O3 particles decomposed from NH4AlO(OH)HCO3 added to the molten Al-Si alloy was described, the microstructure was evaluated by scanning electron......
- PEMFC, Molten carbonate fuel cell - MCFC, Solid oxide fuel cell - SOFC), their development status and economic significance were introduced. Materials and their performance requirements in fuel cell......
of TiAl3 layer and micro-voids existing at the interface.However,through reaction between molten Al and Ti,TiAl3/Ti multilayer can be achieved with complete consumption of Al.During subsequent high......
and blowing process. The viscosity of the molten materials, bio-solubility and crystallization behavior of the fiber were investigated. The results indicated that the fiber drawing temperature range could......
Prediction of the solidification structure of casting and heterogeneous nucleationK.Ohsasa,H.Shirosawa,T.Narita摘 要:<正> The frequency of heterogeneous nucleation during the solidification of Al-Si binary alloy was estimated by comparing experimentally obtained macrostructures of castings with numerically simulated ones. A molten alloy......
, elongated, and irregular) and penetration degrees into the BF coke matrix. The shapes and penetration degrees may depend on the saturation of molten iron by silicon during interaction with the coke......
as the thermodynamic software FactSage 6.2, were used for sample characterization. The results show that the addition of FeO can decrease the viscosity of molten slag and the precipitation temperatures of melilite......
