Abstract Scope |
Equal-channel angular pressing is an established method for the improvement of mechanical properties by grain refinement through shear strains. While there is a profound knowledge about ECAP of bulk materials, there is only little information on the effect of ECAP on sheet metals. Therefore a tool was developed which is able to perform ECAP-tests for metals with a thickness of 1.8 mm. In this contribution a thermomechanical simulation model is used to examine the novel process. The simulation is performed to investigate the dissipated forming heat and the heat due to friction. To validate the numerical results, experiments are performed. By drilling holes in the material the forming temperature can be measured with thermocouples and the friction can be calibrated inversely. In this way, fundamental correlations between the heat development in the ECAP process for Aluminum sheet metal and the shear strain implied in the material can be obtained. |
