Resumo
Aluminium-silicon alloys have been wide accepted in the automotive, electric and aerospace industries.
Preferred orientation is a very common condition for metals and alloys. Particularly, aluminium induces texture
during the forming process. The preparation of an aggregate with completely random crystal orientation is a
difficult task. The present work was undertaken to analyse the texture by X-ray diffraction techniques, of three
spray formed hypereutectic Al-Si alloys. Samples were taken from a billet of an experimental alloy (alloy 1)
and were subsequently hot-rolled and cold-rolled (height reduction), 72% and 70%, respectively. The other used
samples, alloys 2 and 3, were taken from cylinders liners. The results from the Laue camera showed texture just
in the axial direction of alloy 3. The pole figures also indicated the presence of a typical low intensity deformation
texture, especially for alloy 3. The spray formed microstructure, which is very fine, hinders the Al-Si texture
formation during mechanical work.
