Resumo
Hypereutectic aluminium-silicon alloys have been wide accepted in the automotive, electric
and aerospace industries. This is due to the high strength-weight ratio, to the low coefficient
of thermal expansion and the good resistance to the wear and tear. The use of conventional
metallurgy for production of these alloys is limited by a narrow range of possible
compositions. This can be attributed to the formation and presence of coarse primary silicon
particles, because of the slow cooling rate associated to conventional metallurgy. The use of
spray forming can overcome this obstacle. The present work was undertaken to analyse the
texture by X-ray diffraction techniques of three spray formed aluminium-silicon alloys. One
experimental alloy (alloy 1) was hot-rolled and cold-rolled. 'The other two alloys are in
commercial use, alloys 2 and 3. The results from the Laue camera showed texture just in the
axial direction of alloy 3. The pole figures also indicated the presence of deformation texture
just for alloy 3.
