摘要
研究了二元ＭｇＬｉ合金凝固组织与性能，结果表明，二元ＭｇＬｉ合金随Ｌｉ量增加，凝固组织由α→α＋β→β转变。Ｌｉ量小于５７ｗｔ％时为α单相合金，有较好的抗拉强度，极低的伸长率；Ｌｉ量在（５７～１０３）ｗｔ％时为α＋β两相合金，具有优良的综合性能；Ｌｉ量大于１０３ｗｔ％时为β单相合金，有较低的抗拉强度，极高的伸长率。
Abstract A study has been made on the solidified structure to properties and MgLi Binary alloy.The results showed that the solidified structure can be changed from to (+) and with increasing the content of Li.If the Li content is less than 5\^7 per cent by weight,the solidified structure is and it has better ten sile strength and low elongation.If the Li range is from 5\^7 per cent to 10\^3 per cent,the structure is (+) with excellent combined property and if the Li content is over 10\^3 per cent,the structure is ,which has lower tensile strength and higher elongation.
