用透射电镜观察了Ａｌ－Ｌｉ合金淬火组织的位错形态，对已提出的蜷线位错的形成机制进行了评述，并对所研究Ａｌ－Ｌｉ合金中蜷线位错的形成进行了分析．研究结果表明，Ａｌ－Ｌｉ合金中的蜷线位错主要是由受钉扎的位错和弯曲的位错在过饱和空位的作用下攀移形成的．
The dislocation morphology of quenched Al-Li alloy was observed by TEM, and the formation mechanism of the curl dislocation was proposed. The formation of curl dislocation in Al-Li alloy was also analyzed. The results show that the occlusion dislocation in Al-Li alloy is mainly caused by the displacement of pinned dislocations and bent dislocations under the action of supersaturated vacancies.
