本文对铝合金板材拉伸变形时橘皮成因的研究进展进行了评述。首先展示了有无橘皮板材在各种检测仪器下拉伸变形前后的表面形貌、表面滑移带、粗糙度和拉伸断口的形貌，并展示了纳米硬度的测量结果和表征。进一步介绍了最近关于橘皮形成的电子背散射衍射技术（EBSD）的研究成果和X射线对有无橘皮样品的织构测量结果，结合样品的显微组织和力学性能深入分析了橘皮的成因。一系列的结果表明，拉伸变形以后表面橘皮的出现与拉伸变形过程中产生的织构密切相关，而织构的生成又与拉伸过程中晶粒变形的不均匀性有关；晶粒的大小将明显影响变形的不均匀性和织构的生成，粗晶粒比细晶粒更容易产生不均匀变形、晶粒转动和织构，从而导致拉伸变形后生成表面橘皮。由此介绍了粗晶粒和细晶粒拉伸变形后表面状态的示意模型，同时建议对橘皮的形成进行进一步的研究和分析，以完善橘皮成因的定量描述。

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.
