| Abstract Scope |
Equal-channel angular pressing (ECAP) is an established method for the improvement of mechanical properties by grain refinement. While there is a profound knowledge about ECAP of bulk materials, there is only little information on the effect of ECAP on sheet metals. In this contribution the effect of ECAP at different temperatures (20, 75, 150 and 225 °C) and processing routes (A, C and D) on the microstructure and mechanical properties of AA7075 aluminum sheets is investigated. The microstructure is examined using Electron Backscatter Diffraction (EBSD). The results show that microstructural changes and precipitation kinetics could be affected using different configurations. Furthermore, the mechanical properties of the ECAP material is characterized by tensile tests at different temperatures. It was found that the materials strength is controlled by ECAP and the corresponding processing conditions. Due to the specific microstructural features the thermomechanical properties could be considerably improved for future practical applications. |
