Analysis of the Behavior of a Clad Material Al-Zinag-Al

摘要

In the present work, we studied the nanostructural behavior of a denominated alloy Clad-Zinag, which is composed of a single layer of Zinag coated on both surfaces by an aluminum film. The alloy was then deformed by two different processes, one in which a superplastic conformed technique was applied and the second was by way of tensile testing. For both techniques, the alloy was examined and analyzed by viewing the materials topography with an atomic force microscope (AFM). From these techniques we were able to observe both processes of plastic deformation and the presence of marks which correspond to bands of grain sliding. This mechanism is a result of superplastic deformation, and influences the grain size of aluminum. Nevertheless, we must clarify that the name of mesoscopic band of slides, is based on a study according to Vinogradov.
