Microstructure and texture in 6016 aluminum alloy during hot compression were researched with a uniaxial compression experiment. Through the electron backscattered diffraction(EBSD) and X-ray diffraction(XRD)analysis technology, it is shown that the subgrain nucleation and recrystallization occur in 6016 aluminum alloy during hot compressing, and strong rolling textures such as h110 i fiber texture, Brass, S, and Goss form. With the deformation passes increasing, h110 i fiber texture, Brass and S are enhanced. In the heat preservation stage after deformation, recrystallization continues until heat preservation for 60 s, and a duplex microstructure of deformation and recrystallization grains is built. At the beginning of heat preservation, recrystallization grains with the Goss texture and random orientation are formed in original grains with S or Brass texture, which makes the volume fraction of S and Brass texture decrease. Then, the complex grain growth process makes the volume fraction of Brass,S, and Goss texture increase, while that of random orientation decrease.
