Texture Evolution and Plastic Strain Ratio in 5083 Aluminum Alloy Processed by Cold Forging

摘要

5083 aluminum alloys were cold-forged to study the possibility of enhancing the formability and reducing the planar anisotropy. Texture evolution during cold forging was discussed with pole figure and orientation distribution function (ODF). The formability and planar anisotropy in forged 5083 aluminum alloys were evaluated in terms of the r-value (plastic strain ratio or Lankford parameter) which was not only calculated from the measured pole figures but also measured in direct by tensile tests. The {110} fiber texture was developed during cold forging, by which the 5083 aluminum alloy having high formability and low planar anisotropy could be produced.
