China 22(2012) 2312-2319 Effect of uniform magnetic field on crystallization of intermetallic compound layers between Cu and liquid SnZn alloys CHENG Cong-qian1, 2, HUANG... of Technology, Dalian 116085, China Received 5 September 2011; accepted 22 November 2011 Abstract: Crystallization of intermetallic compound layer between Cu and SnZn alloy under uniform magnetic field......
magnetic field distribution for the system were studied. In addition, the mathematical model of driving torque and space magnetic field of the three alveolar stator were created. The mathematical... magnetic field were verified through experiment. The results show that the driving torque and space magnetic field mathematical model is correct. It is stable in the operation of axial flow blood pump......

with a constant magnetic field applied outside the boundary layer parallel to the plate was investigated.The governing system of partial differential equations was transformed to ordinary differential... coefficient,velocity profiles,and the induced magnetic field profiles were obtained for some values of the moving parameter,magnetic parameter,and reciprocal magnetic Prandtl number.The results indicate......
the effect of alternating magnetic field on austenite transformation process in the case of rapid heating, the austenite kinetics model of AISI 1045 steel was built for spot continual induction hardening (SCIH) process. The results shows that the effect of alternating magnetic field on austenite transformation fraction reaches the maximum (about 3%) when heating rate is the lowest. Relatively low......
复合磁场作用下金属液面行为的实验研究邓安元1,王恩刚1,徐永义1,张兴武1,赫冀成1(1.辽宁省沈阳市东北大学材料电磁过程研究教育部重点实验室)摘 要:以低熔点Sn-32%Pb-52%Bi合金作为模拟介质,实验研究了高频交变磁场以及复合磁场(交变磁场+静磁场)作用下结晶器内液面波动及其不稳定行为.实验发现,单独施加交变电磁场时,液态金属表面处于波动状态,随着交变磁场磁感应强度增加,液面会依次出现稳定凸起圆台形变形和液柱的随机摆动现象;发生摆动时的凸起液面主要呈柱状和三棱柱状,此时液面中心波动略强于三相点处.随交......

Effect of an upward magnetic field on nanosized sulfide precipitation in ultra-low carbon steelKang-jia Duan1,Ling Zhang2,Xi-zhi Yuan1,Shan-shan Han1,Qing-song Huang11. School of Chemical Engineering... and is rotated under an upward magnetic field. With the addition of Ti additives, the spinning molten steel under the upward magnetic field ejects particles because of resultant centrifugal, floating......
materials under influence of the magnetic field in the adiabatic conditions. When magnetic materials containing atoms that carry magnetic moments are placed in an external magnetic field, the magnetic field forces magnetic moments to align, reducing the magnetic entropy, which makes magnetic materials heat up. Conversely, when the materials are taken out of the magnetic field, the magnetic......
6.5 wt% Si high silicon steel sheets was proposed by combining composite electrodeposition(CED) and diffusion annealing under magnetic field. The obtained sheets were characterized by scanning... current efficiency and the silicon content of coatings were obviously influenced by the micro and macro magnetohydrodynamics(MHD) flows under magnetic field.With the effect of magnetic field......
