On the texture of aluminum rods extruded under various conditions

Abstract

The texture of aluminum rods developed by the extrusion under various conditions was studied. The tests were conducted by varying extruding temperature, position of rod, and angle of dying. The results obtained were as follows.
(1) Extruded aluminum rod showed cyclic fibrous structure, and the planes having high degree of texture were (112) [111], (213) [111], (178) [111], (001) [100], and (012) [100].
(2) The amount of <100> structure component was larger with the rise of extruding temperature, and that at the middle part of the rod (250mm from the tip) was greater than that at its front end (60mm from the tip), which showed that the amount gradually increased from the end to the middle owing to the recrystallization during extrusion.
(3) In the position adjacent to the angle of dying, the amount of <100> component was larger with the increase of angle.
