; Abstract: Numerical simulation based on phase field method was performed to describe the solidification of silicon. The effect of anisotropy, undercooling and coupling parameter on dendrite growth shape... to facet dendrite. In addition, with increasing coupling parameter, the facet part of facet dendrite decreases gradually, which is in good agreement with Wulff theory. Key words: phase field method; facet......
Microscopic Phase Field Study of the Spinodal Decomposition in Fe-Mo Alloys朱景川,赵荣达School of Materials Science and Engineering,Harbin Institute of Technology摘 要:The spinodal decomposition in Fe-Mo alloys is studied by microscopic phase field method based on atomic scale.The results show that critical temperature of spinodal decomposition increases......
Effect of External Electric Field on Phase Selection and Stability of Amorphous( Nd0.1Fe0.9 )3 B Alloy 都有为1,顾本喜1,李山东1,袁钻如3,唐建成2 (1.Depantment of Physics, Fujian Normal University, Fuzhou 350007...) Abstract:The effect of an external electric field on the crystallization behavior of amorphous(Nd0.1Fe0.9)3B alloy was investigated. The crystallization product of Nd2Fe23B3 phase was obtained......
2.1 Model of phase field theory Phase field theory provides a powerful method for predicting the temporal evolution of the ferroelectric domain microstructure. The ferroelectric undergoes... on the time-dependent Ginzburg-Landau (TDGL) equation, the temporal evolution of the domain structure and hysteresis loops of polarization versus electric field were simulated by a phase-field model......
Integration of machine learning with phase field method to model the electromigration induced Cu6Sn5 IMC growth at anode side Cu/Sn interfaceAnil Kunwar1,Yuri Amorim Coutinho1,Johan Hektor2,3,Haitao... growth rate constants (kem) of the anode IMC at several magnitudes of applied low current density (j=1×106to 10×106A/m2) are extracted from simulations based on a 1D multi-phase field model.A neural......
and phase separation method [7, 8]. The liquidus temperatures and phase relations of Ti-bearing slag are necessary to facilitate improvements to the related processes. However, the phase diagrams were... of above mentioned system. The traditional way of phase diagrams investigation is the high-temperature equilibrium and quenching method, which exhausts a large amount of time. In the present work......
Trans. Nonferrous Met. Soc. China 24(2014) 783-789 Thermodynamic consistent phase field model for sintering process with multiphase powders Rui-jie ZHANG1, Zhong-wei CHEN2, Wei FANG1, Xuan-hui QU1,3... 2013 Abstract: A thermodynamic consistent phase field model is developed to describe the sintering process with multiphase powders. In this model, the interface region is assumed to be a mixture......
