Structure and Growth Mechanism of Lanthanum Chromate Fu Guifu1,Ao Qing1,Liu Weiming1,SUN Liangcheng1,Li Shengli1,Ling Ziyu1 (1.Department of Materials Science and Engineering, Shandong University.... The growth mechanism was discussed in terms of structural ledge observed by SEM, the surfaces of the structural ledges parallel to (001), (010) and (110) planes, respectively. The misfit between (110......
Effects of RE and Sr additions on dendrite growth and phase precipitation in AZ91D magnesium alloy ZHOU Ji-xue(周吉学), WANG Jie(王 杰), WANG Jing(王 晶), YANG Yuan-sheng(杨院生) Institute of Metal... of rare earth (RE), Sr and RE + Sr on the dendrite growth and phase precipitation in AZ91D magnesium alloy were studied, respectively. The results show that the microstructure is refined......
Growth behavior of ultrafine austenite grains in microalloyed steel Shengjie YAO1,Linniu DU1,Guodong WANG1,Xianghua LIU1 (1.State Key Laboratory of Rolling and Automation,Northeastern University,Shenyang 110004,China) Abstract:Ultrafine austenite grains (UFAGs) with size of 1-5 μm were prepared through repet-itive treatment, four times, of rapid heating and quenching, and the growth behaviors......
Article ID: 1003-6326(2005)06-1214-05 Growth characteristics of MoS2 coatings prepared by unbalanced bipolar DC magnetron sputtering WANG Ji-hui(王吉会)1, XIA Yang(夏 扬)1, E.Wieers2... argon pressures turn to grow with the mixed basal and edge orientations. The morphology and structure of MoS2 coatings are highly related to their growth rate and the energy of sputtered particles......
Trans. Nonferrous Met. Soc. China 22(2012) 2212-2219 Modeling of equiaxed and columnar dendritic growth of magnesium alloy WU Meng-wu1, 2, XIONG Shou-mei1, 2 1. Department of Mechanical Engineering... Abstract: Based on the cellular automaton (CA) method, a numerical model was developed to simulate the dendritic growth of magnesium alloy with HCP crystal structure. The growth kinetics was calculated......
Growth of Superconducting Whiskers葛云龙,刘清民,金华,常昕摘 要:<正> The(1112)and(2212)amorphous strips ofBi(Pb)-Sr-Ca-Cu oxide were prepared bynon-equilibrium solidification of melt-quenchingmethod.A lot of superconducting whiskers havebeen grown up on the strip at 840-860°C in astream of oxygen for 50-150 h,which are usuallyseveral to 10 odd mm in length......
