Abstract

The severe plastic deformation technique that has attracted much attention from the material community in recent years is Equal Channel Angular Pressing (ECAP). By using this technique, ultrafine-grained microstructures can be produced without a significant change in the geometry of the material. In the present research, an aluminum 6063 sample was tensile tested after the ECAP process to know the properties of the material. ECAP is performed for two sets of specimens in which the channel angle is 108. One set of samples is at room temperature, and the other set is at -197oC, i.e., dipped in liquid nitrogen for 20 minutes. Tensile properties of the obtained samples are tested once more. The tensile test properties of samples, i.e., before processing and after Room Temperature (RT) and CRYO ECAP, are tabulated and saved for simulation. A rivet with American Society for Testing and Materials (ASTM) dimensions is designed using a design modeller in Analysis of Systems (ANSYS), and the properties obtained from the tensile tests are assigned to the rivet. One end of the rivet is constrained with a fixed support, and the other end is loaded with 35 kN in the downward direction. The process is repeated for three different sets of samples. The developed stresses in the three rivets are tabulated and correlated, and the results are drawn in the present investigation, which showed good correlation.
