| Abstract Scope |
Ultrafine grained materials can be produced through severe plastic deformation methods such as the friction assisted lateral extrusion process (FALEP). By FALEP, one can bond different metals into a layered-sheet and obtain lighter structures with new properties. Such multilayer structure has residual stresses which can influence fatigue strength and formability of the material. FALEP experiments were carried out on Al-1050 and Al 5052 alloys, as well as on Al-1050 and copper. The residual stresses were measured by X-ray, using the Debye ring technique and were related to the parameters of the materials and processing technique. |
