Study of the Texture of Aluminum Alloys after Cold Rolling, Annealing, and Irradiation by Ar+ Ions

The crystallographic texture of samples (1-3 mm thick) of AMg6, VD1, and 1441 aluminum alloys has been studied after cold rolling, post-rolling annealing, and irradiation by accelerated Ar+ ions (E = 20-40 keV). A feature in common for the {200} and {111} pole figures of samples rolled to a medium degree of reduction (35-72%) is the absence of the pole density at the center of these figures. When the alloys under study undergo post-rolling technological furnace annealing at high temperatures, a texture is formed with a scattered main component of the {001}< 100 > type, which also occasionally contains orientations from scatter regions of the rolling-texture components. An exposure of the cold-deformed samples to a beam of accelerated Ar+ ions generally leads to analogous textural changes (in the whole volume of the samples irradiated from one side) in a much shorter time and, most frequently, at temperatures 100-200 K lower than in the case of the furnace annealing. In the 1441 alloy, the formation of an unusual two-component cube {001}<< 210 > texture has been noted.
