The effect of homogenization conditions on extrusion texture and microstructure evolution in AA3003

Two different conditions were used to study the effect of homogenization on extrusion texture and microstructure evolution in AA3003. The first condition considered homogenization for 8h at 500 degrees C to obtain a high density of dispersoids and the other condition was homogenized for 24 h at 600 degrees C to produce a sample with a very low density of dispersoids. After uniaxial extrusion at 400 degrees C with a speed of 32 mm/s and extrusion ratio of 70: 1, the material with a high density of dispersoids formed <001> and <111> double fibre texture in the centre of extrusion rod and a smeared texture from <011> to <111> near the surface. For the material without dispersoids, only <001> texture fibre is observed in the centre of extrusion rod and a strong <011> fibre is observed near the surface.
