Title
Residual Stresses in Surface Layer of Cold Drawn 5056 Aluminum Alloy and Alclad 5056 Aluminum Alloy Wires
박석완Suk Wan Park, 이동녕Dong Nyung Lee
Abstract
A study has been made of residual stresses in the surface layer of heavily cold drawn 5056 aluminum alloy wire and 6253 aluminum alloy clad (clad cross section ratio: 10-30%) 5056 aluminum alloy wires. For this purpose, an X-ray stress analysis was applied. The residual stresses were evaluated under an assumption of isotropy. The 5056 aluminum alloy wire had tensile residual stresses. The same alloy wires, however, exhibited compressive residual stresses when they were clad in a softer 6253 alloy.
