In this PhD-thesis, the studied material is an aluminium alloys 5182 containing two particles types: Alx(Fe,Mn) and Mg2Si. During industrial rolling, particles are broken up, and redistributed in the volume of the sheet.As particles controls surface aspect and formability of the final sheet, the work presented is based on two issues: to highlight volume distribution of intermetallic particles, and to characterize their three-dimensional shapes during the rolling process. Thus, samples extracted to different steps of the rolling process are been scanned by X ray micro tomography (performed at the ESRF). The obtained three dimensional images are segmented by a multi class thresholding method. Extraction of each particle type is allowed. A dat...
