چکیده انگلیسی
Twin roll casting is an established route to produce aluminium sheet (10-0.5 mm thick) directly from the melt. Various microdefects (bleeds, centre segregates, â¦) and inappropriate texture arise during casting which limit the range of operating conditions suitable for use commercially. In this study, the as-cast texture gradient running from a shear texture ([1 0 0]ã0 1 1ã and [1 1 1]ãuvwã) in the sub-surface towards a weak β-fibre in the centre has been investigated. During the first stages of cold rolling, the surface shear components rotate towards stable rolling orientations; meanwhile, hard eutectic-like structures in the centre segregates are not affected by the deformation; only, the surrounding Al-matrix is subjected to a high level of plastic deformation. On the other hand, the surface bleed (where a high density of hard intermetallic has been found) follows the overall behaviour of the Al-matrix. This behaviour is mainly due to the fine primary α-Al structure inside the bleed that is able to sustain a large amount of cold deformation (up to 95%) without cracking.
