Interfacial Characteristic of as-Deformed SiCp-Reinforced Magnesium Matrix Composite

引用

Acta Metallurgica Sinica(English Letters) 2014年第5期27卷 885-893页

作者： Kun Kun Deng jian Chao li jian Feng Fan Xiao Jun Wang Kun Wu Bing She Xu College of Materials Science and Engineering Taiyuan University of Technology Key laboratory of interface science and engineering in advanced materials Ministry of EducationTaiyuan University of Technology School of Materials Science and Engineering Harbin Institute of Technology

The （submicron ＋ micron） SiCp-reinforced magnesium matrix composite was fabricated by stir casting. After the application of forging and extrusion, the interface between SiCp and Mg in the composite was investigated by transmission electron microscopy. Results show that the interfacial characterization was different at the interfaces of micron-SiCp/Mg and submicron-SiCp/Mg. While most interfaces between micron-SiCp and Mg were clean, the precip- itated Mg17A112 phase as well as dispersedly distributed nano-MgO particles was observed at some interfaces. Unlike the interface between micron-SiCp and Mg, no interfacial reaction product was found at the interface between submicron-SiCp and Mg in the present study. Besides, the specific orientation relationships were found at the interfaces between submicron- SiCp and Mg, which was thought to have developed during hot deformation process. At the fracture surface of the composite, the microcracks were found at the interface between micron-SiCp and Mg, while the interfacial bonding between submicron-SiCp and Mg was very well.

OO Aquilae:a solar-type contact binary with intrinsic light curve changes

引用

Research in Astronomy and Astrophysics 2016年第1期16卷 13-22页

作者： Hua-li li jian-Yan Wei Yuan-Gui Yang Hai-Feng Dai Key Laboratory of Space Astronomy and Technology National Astronomical ObservatoriesChinese Academy of SciencesBeijing 100012China University of Chinese Academy of Sciences Beijing 100049China School of Physics and Electronic Information Huaibei Normal UniversityHuaibei 235000China

New multi-color photometry of the solar-type contact binary OO Aql was obtained in 2012 and2013, using the 60 cm telescope at Xinglong Station of the National Astronomical Observatories, Chinese Academy of Sciences. From two sets of light curves LC_1 and LC_2, photometric models were performed by using the 2003 version of the Wilson-Devinney code. The overcontact factor of the binary system was determined to be f = 37.0（±0.5）%. The intrinsic variability of this binary occurs in light maxima and minima, which could result from a possible third component and magnetic activity of the late type components. Based on all available light minimum times, the orbital period may change in a complicated mode,i.e., sudden period jumps or continuous period variations. The period of OO Aql may possibly undergo a secular period decrease with a rate of d P /dt =-3.63（±0.30） × 10^（-8）d yr^（-1）, superimposed by two possible cyclic variations in the O- C curve. The long-term period decrease may be interpreted as conserved mass transfer from the more massive component to the less massive one. The 21.5-yr oscillation may be attributed to cyclic magnetic activity, and the 69.3-yr one may result from the light-time effect of an unseen tertiary body.

THE INFLUENCES OF SSTA OVER KUROSHIO AND ITS EXTENSION ON RAINFALL IN NORTHEAST CHINA UNDER THE BACKGROUND OF TWO DIFFERENT EL NIO CASES

引用

Journal of Tropical Meteorology 2018年第2期24卷 232-242页

作者： WANG Qin li Shuang-lin FU jian-jian Civil Aviation Flight University of China Guanghan Sichuan 618307 China Institute of Atmospheric Physics Chinese Academy of Sciences Beijing 100029 China

By using the gauged rainfall in 160 stations within China's Mainland and the NCEP/NCAR reanalysis data, the impacts of anomalous SST in Kuroshio and its extension on precipitation in Northeast China were investigated. The results show that a difference in the meridional circulation such as the East Asia/Pacific teleconnection pattern(EAP)may be responsible for the difference in rainfall between 1998 and 2010. In comparison with 1998, the anomalous meridional circulation pattern in 2010 shifted northeastward, and then the western subtropical high, the mid-latitudinal trough and the northeastern Asia blocking high also shifted northeastward, causing intensified convergence of the cold and warm air masses at the southern region and thus more rainfall in the southwestern region and less in the northwestern region. In 1998, the anomalous cyclone, one component of the meridional pattern, located at the Songhuajiang-Nengjiang River basin, resulted in more rainfall in the majority of the area. The results of observation and the model show that the difference in SSTA in Kuroshio and its extension under the background of different El Ni觡o events is the key point:(1) The anomalous warmth moved westward from the mid-Pacific to the east of the Philippine Sea during the central event, which led the heat resources shifting to the northeast in 2010; subsequently, a shift occurred to the north of the anomalous ascent and decent, followed by a warm SSTA in the region of Kuroshio's extension in 2010 and Kuroshio in 1998.(2) The warm SSTA in the Kuroshio extension causing the Rossby wave activity flux strengthened in 2010, and then the westerly jet shifted northward and extended eastward. A warm SSTA in Kuroshio and cold SSTA in its extension in 1998 caused the westerly jet to shift southward and weaken. As a result,the anomalous anticyclone and cyclone shifted northward in 2010, and the blocking high also shifted northward.

采用显微镜金相分析方法,对磨球钢超声探伤不合格的位置进行取样检验和分析。结果表明,钢材内部有裂纹,主要由两方面原因造成:一是连铸坯局部位置存在较严重的中心疏松,在轧制过程未焊合所致;二是连铸开浇炉钢水易与空气接触,吸收空气中的水分或气体,在钢水凝固成铸坯加热轧制后,气体析出聚集在心部,与组织应力共同作用,导致圆钢心部开裂。针对原因提出了相对应的工艺改进措施。
