摘　　要：7A04CS合金管材阳极氧化后颜色不均匀,通过对管材组织特征的观察和模拟试验,确定管材中某些部位存在大量的亚晶粒,它是造成颜色发黑的根本原因。对其形成的机理和消除它的办法进行了阐述。The tube colour is not uniform after anodizing. It is sure that there are a lot of subgrains in some sections of the tube, which is the basic cause of bringing about that the tube colour turns into the black, through the investigation and the simulation test to the macrostructure characteristics of the tube, the fonnation mechanism about the subgrains and the methods to eliminate them are explained.
