共晶生长共晶生长eutectic growth 晶面共晶称为反常共晶。金属一非金属共晶属于这类共晶,其微结构是不规则或复杂规则的形态。③a相与刀相的熔化摘都很高,是小晶面一小晶面共晶。非金属与非金属的共晶属于这一类。这类共晶在生长时,虽然两个相几乎同时从液相析出,但两者互不相干,独立地生长,其最终的微结构是两相紊乱排列的混合体。 A、B组元组有规则层状组织 b有规则杆状组织图1正常共晶微结构示意图成的共晶系,定向凝固液相成分为共晶成分的合金。在一定过冷度下,若先成核的领先相为a,其含B组元的浓度低于共晶浓度,则在a相从液相中成核、成长过程中排出B组元,促使含B浓度高的刀相在a相上成长。在刀相附近的液相成分有利a相生长,于是就形成a相和刀相的交替组织。共晶中两相交替成长,不是独立地重新成核,其成长过程是靠搭桥方式,使同类相的层片连在一起增殖。在凝固过程中,两个组成相的固一液界面并排地向液相推进,两相排出的组元,通过横向扩散(图2),促使另一相成长。这种扩散是靠两相不断成长来维持的,两相互相影响,祸合生长。 K.A杰克逊图2共晶成长界面前沿熔体中 溶质的横向扩散(Jaekso司和D.J,亨特(Hunt)对正常共晶的祸合生长,作了定量描述。通过求解二维扩散场的稳定扩散方程,求出满足边值条件的解,得到稳态生长情况下辊合生长固一液界面前沿液相中的溶质分布。计算了层状共晶界面曲率和界面上溶质浓度与共晶浓度的偏离引起的界面温度与共晶温度之差,从而得到界面上过冷度△T ~,,.B凸1二了it从十一万 八式中夕为生长速率,月为层片之间距离(a相与刀相交替分布的周期),A和刀对于一定的生长系统是常数。生长速率为一定时,△T与穴的关系见图3。图中出现一个与最小过冷度对应的凡。凡就是这个生长速率的共晶层周期。
