摘要
Abstract
Using phase field to simulate the dendrite growth of Fe-0.5 mol％C alloy during isothermal solidification,the effects of the anisotropy on dendrite growth were studied.By comparing the corresponding dendritic morphology under different anisotropy coefficient of 0.00,0.06 and 0.08,the applicable range of anisotropy coefficient of the experimental material was obtained,it is 0.00 to 0.06,and in this range,with the increase of anisotropy coefficient,the dendrite arm spacing decreases,the dendrite tip growth rate gradually increases,the curvature radius of dendrite tip reduce in order.关键词
