Orientation coherence of rolled and annealed aluminum plate
Change of spatial orientation distributions is investigated in 95 % cold rolled aluminum plates annealed at 300degreesC temperature for 10, 60, 180 and 300 seconds. Spatial distribution of orientations is measured by Electron Back Scattered Diffracting (EBSD) technique and spatial correlation of orientations is calculated using the two-point orientation coherence function (OCF). the orientational relationship around each main orientation can be found as a function of annealing time. Copper, S and brass components are initially distributed in mixture as thin bands but as annealing time increases to 300 seconds, S and brass components form distinct bands wider than 5 Am along sample normal direction and copper component exists in the brass bands.
