| 摘 要： | 本文研究了定向凝固参数对二元铝锂合金共晶生长及组织结构的影响。实验发现，Ｌｉ少于７ｗｔ％的合金中，晶体不能以共晶方式生长。Ｌｉ多于７ｗｔ％的合金中，可以获得平面生长的共晶组织，凝固参数对晶体生长方式及组织形貌有显著的影响

| Abstract: | The effect of directional solidification parametor on eutectic growth and structure of binary Al Li alloy was studied. It is discovered that eutectic structure can not be obtained when Li content is less than 7wt%, the ectectic structure with planar front can be obtained when Li content is more than 7wt%, and solidification parameter is of important effect on growth type and structure morphology. |
