Research progresses of forming causes for orange peel during the tensile deformation of aluminum alloy sheet are reviewed. This paper first shows the surface morphology of tensile deformation of sheets with orange peel and non orange peel，sliding zone，roughness of surface，tensile fracture morphology and nano hardness measurement results and characterization. Recent research results of electron backscattered diffraction（EBSD）using the forming causes of orange peel and the texture measurement results of orange peel and non orange peel using X-ray are further introduced. According to the mentioned results，microstructure and mechanical properties，the forming causes of orange peel are analyzed further. A series of results show the appearance of orange peel surface after tensile deformation is closely related to the texture and grain orientation caused in tensile deformation. The texture generating is closely related to inhomogeneity deformation of grain. Grain size will significantly affect the inhomogeneity deformation and the formation of texture ； coarse grain is easier to cause inhomogeneity deformation，grain rotation and texture than that of fine grain，resulting in surface orange peel forming after tensile deformation. Thus，it introduces a model of surface state of the coarse grain and fine grain after the tensile deformation. It is also suggested that the formation of orange peel should be further researched and analyzed so as to perfect the quantitative description of orange peel formation.
