The Influence of Natural Convection and Electromagnetically Driven Flows on Segregation Freckle Formation
《Journal of Iron and Steel Research International》2012年第S1期459-462,共4页Shevchenko Natalia Boden Stephan Eckert Sven Gerbeth Gunter 
Item Sponsored by Deutsche Forschungsgemeinschaft (DFG) in frame of the SFB 609"Electromagnetic Flow Control in Metallurgy;Crystal Growth and Electrochemistry"
Visualizations of the solidification process were obtained by means of X-ray radioscopy within a Hele-Shaw cell filled with a Ga-25wt%In alloy.Therrno-solutal convection in the solidifying melt gives rise to the devel...

2-Dimensional FEM modeling of macrosegregation in the directional solidification with mesh adaptation
《Acta Metallurgica Sinica(English Letters)》2009年第3期233-240,共8页Weitao LIU Changchuan XIE Michel Bellet Hervé Combeau 
In order to improve the prediction accuracy of macrosegregation channel, an algorithm for dynamic remeshing is proposed. The basic idea is to generate fine elements near the liquidus isotherm. The norm of the gradient...
