利用透射电子显微镜和计算机图像模拟技术研究了Ll型Ａｌ３Ｔｉ合金室温变形的位错核心结构，结果表明：ａ（１１０）超位错在｛１１１｝面上分解成两个ａ／３（１１２）型超偏位错，其间为超点阵内禀层错
The dislocation core structure of room temperature deformation of L1 Al3Ti alloy has been investigated by transmission electron microscopy and computer image simulation. The results show that a (110) super-dislocation decomposes into two a / 3 (112) Super-offset error, during which superlattice intrinsic layer fault
