Fitting function representation for strain fields and its application to the optimizing process
International Journal of Minerals, Metallurgy, and Materials - Tập 21 - Trang 556-562 - 2014
Kun Chen, Ke-jia Liu, Li-qun Wei, Yi-tao Yang
A fitted function method to describe the strain fields during forging was discussed to optimize the homogeneous distribution of strain in the axial forging zones during successive stretching. The results are verified by experiment and numerical simulation, and the deviations between experiment and simulation are less than 24%. Therefore, the fitted function method can be applied to optimize the st...... hiện toàn bộ
Channel effect of the modified powdery mixture of ammonium nitrate and fuel oil
International Journal of Minerals, Metallurgy, and Materials - Tập 17 - Trang 519-525 - 2010
Chun-ping Wu, Lian-sheng Liu, Xu-guang Wang, Yong Liu, Yin-jun Wang
The modified powdery mixture of ammonium nitrate and fuel oil (MPANFO) is a new breed of industrial explosives developed years ago in China. As one of the important properties of an industrial explosive, the channel effect of MPANFO was reported in this paper. A series of experiments were conducted to determine the channel effect of MPANFO. The blasthole diameter range was estimated to avoid the c...... hiện toàn bộ
Coordinated control of carbon and oxygen for ultra-low-carbon interstitial-free steel in a smelting process
International Journal of Minerals, Metallurgy, and Materials - Tập 22 - Trang 1252-1259 - 2015
Min Wang, Yan-ping Bao, Quan Yang, Li-hua Zhao, Lu Lin
Low residual-free-oxygen before final de-oxidation was beneficial to improving the cleanness of ultra-low-carbon steel. For ultra-low-carbon steel production, the coordinated control of carbon and oxygen is a precondition for achieving low residual oxygen during the Ruhrstahl Heraeus (RH) decarburization process. In this work, we studied the coordinated control of carbon and oxygen for ultra-low-c...... hiện toàn bộ
Recent progress in the structure optimization and development of proton-conducting electrolyte materials for low-temperature solid oxide cells
International Journal of Minerals, Metallurgy, and Materials - - 2022
Jia Song, Yuvraj Y. Birdja, Deepak Pant, Zhiyuan Chen, Jan Vaes
This work reviews technologies that can be used to develop low-temperature solid oxide cells (LT-SOCs) and can be applied in fuel cells and electrolyzers operating at temperatures below 500°C, thus providing a more cost-effective alternative than conventional high-temperature SOCs. Two routes showing potential to reduce the operating temperature of SOCs to below 500°C are discussed. The first rout...... hiện toàn bộ
Microstructure of Ni–Al powder and Ni–Al composite coatings prepared by twin-wire arc spraying
International Journal of Minerals, Metallurgy, and Materials - Tập 23 - Trang 810-818 - 2016
Ji-xiao Wang, Gui-xian Wang, Jing-shun Liu, Lun-yong Zhang, Wei Wang, Ze Li, Qi-xiang Wang, Jian-fei Sun
Ni–Al powder and Ni–Al composite coatings were fabricated by twin-wire arc spraying (TWAS). The microstructures of Ni-5wt%Al powder and Ni-20wt%Al powder were characterized by scanning electronic microscopy (SEM) and energy dispersive spectroscopy (EDS). The results showed that the obtained particle size ranged from 5 to 50 μm. The morphology of the Ni–Al powder showed that molten particles were c...... hiện toàn bộ
Low-temperature densification sintering and properties of CaAl2Si2O8 ceramics with MeO·2B2O3 (Me = Ca, Sr, Ba)
International Journal of Minerals, Metallurgy, and Materials - Tập 22 - Trang 977-986 - 2015
Song Chen, De-gui Zhu
Dense CaAl2Si2O8 ceramics were prepared via a two-step sintering process at temperatures below 1000°C. First, pre-sintered CaAl2Si2O8 powders containing small amounts of other crystal phases were obtained by sintering a mixture of calcium hydroxide and kaolin powders at 950°C for 6 h. Subsequently, the combination of the pre-sintered ceramic powders with MeO·2B2O3 (Me = Ca, Sr, Ba) flux agents ena...... hiện toàn bộ
Design and calculation of low infrared transmittance and low emissivity coatings for heat radiative applications
International Journal of Minerals, Metallurgy, and Materials - Tập 19 Số 2 - Trang 179-184 - 2012

Interactions of molten salts with cathode products in the FFC Cambridge Process
International Journal of Minerals, Metallurgy, and Materials - Tập 27 Số 12 - Trang 1572-1587 - 2020
George Chen
AbstractMolten salts play multiple important roles in the electrolysis of solid metal compounds, particularly oxides and sulfides, for the extraction of metals or alloys. Some of these roles are positive in assisting the extraction of metals, such as dissolving the oxide or sulfide anions, and transporting them to the anode for discharging, and offering the high te...... hiện toàn bộ
