An important consideration for Al-Mg-Si 6xxx alloys that are to be used as outer panels for car body applications is the surface appearance of the final parts. The development of paintbrushes lines on the surface of aluminium sheets - commonly referred to as ridging or roping - has been linked to the presence of bands of similar crystallographic orientations in the sheets, i.e., to a pronounced texture. Bands of similar orientations tend to deform collectively under formation of elevated or depressed band-like regions. Thus, in severe cases, the texture bands result in surface roughening which may degrade forming limits and can be unacceptable for paint finish. In order to avoid ridging, the texture sharpness of the sheet in final T4 temper needs to be controlled using appropriate processing schedules. The present paper presents the results of laboratory scale experiments on the correlation of texture and ridging. A variety of sheets with different textures in T4 temper has been produced through various thermomechanical processings. Ridging is analysed optically and quantified by means of roughness measurements (both line scans and area scans). The spatial correlation of the recrystallisation texture components, i.e. the orientation topography, is determined by automated large-scale EBSD mapping.
