摘要：

Texture evolution in extruded and hot-rolled Al-Mg-Li aeronautical alloys during in-situ tension was investigated by using electron backscattered diffraction (EBSD). A field emission scanning electron microscope (FE-SEM) and a MICROTEST-5000 tensile stage were used to carry out in-situ tension tests and observations. The crystallographic texture of the extruded sample changed from weak cube texture {001}aOE (c) 100 > to texture {018}aOE (c) 081 > during tension fracture. However, strong Brass {110}aOE (c) 112 > in the hot-rolled sample was modified into a mixture texture component of Brass {110}aOE (c) 112 > and S {123}aOE (c) 634 > during tension fracture. Texture evolution in the two samples during tension can be explained by the rotation of grain orientation.
