【摘要】 阐述了多相场法模拟共晶凝固原理和研究现状。多相场模型经历了从纯物质晶粒到多元多相合金 ,从各向同性到各向异向 ,从等温模拟到非等温模拟的发展过程。并指出进一步的研究方向 ,认为未来将是发展包括流场、应力场以及其他场作用的共晶多相场模型。更多还原

【Abstract】 Theory and present research status of numerical simulation for eutectic solidification with multi-phase field method were expounded. The multi-phase field model has experienced the development stages from pure material grain to multi-phase and multinary alloy, from isotropy to anisotropy,from isothermal temperature to aniso-thermal temperature. The further research prospects were pointed out.It is suggested that flow field and stress field as well as other fields would be considered in future trendency of the multi-phase field model.更多还原
