本文在定向凝固系统上用变速抽拉方法试验研究了Al-Si共晶强制非稳态生长过程。在加速生长过程中,共晶相间距对生长速度的响应呈滞后效应,响应机制是共晶Si相成簇分枝和局域“终结”延伸。在减速生长过程中,Si相成簇分枝和“终结”伸缩机制仍控制相间距;共晶相间距由初始生长速度决定,对生长速度下降不产生响应...

Nonstable growth of Al-Si eutectic in constrained condition has been investigated by means of change of the withdrawing rate in an unidirectional solidification system,In constant acceleration growth,a retarded effect of response of eutectic interflake spacing on the growth rate has been observed.Th...
