摘要
利用高分辨电镜(HRTEM)和常规电子显微术研究了快速凝固Al-Li-Cu—Mg—Zr合金中Z相和T相的结构关系,发现两相间两种确定的晶体学取向关系,并以此为依据解释了Z相和T相的某些结构缺陷两相的结构有密切关联。
Structural relationship between Z and T phases in a rapidly solidified
Al-Li-Cu-Mg-Zr alloy has been studied by high-resolution electron microscopy and
conventional tramission electron microscopy. The result shows that there exist two well de-
fined orientation relationships between Z and T phases. The observed structural faults in Z
and T phases could be interpreted. The structrues of the two phases is closely related to each
other, certain faulted structures in one phase can be seen as the other phase when the faulted
area is extended.
