摘      要：Texture evolution in extruded and hot-rolled Al-Mg-Li aeronautical alloys during in-situ tension was investigated by using elec-tron 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}〈100〉 to texture {018}〈081〉 during tension fracture. However, strong Brass {110}〈112〉 in the hot-rolled sample was modi-fied into a mixture texture component of Brass {110}〈112〉 and S {123}〈634〉 during tension fracture. Texture evolution in the two samples during tension can be explained by the rotation of grain orientation.
