(AFSD) Additive friction stir deposition is a novel solid-state forming method that can form isotropic material structures without solidification defects and the forming characteristics of the forming area and the forming thermal process in AFSD can significantly change the performance of the workpiece, therefore the thermal analysis of the forming process in AFSD is particularly important. The simulation of AFSD thermal process of AA6061-T6 aluminum alloy is missing. In this study, the cell life and death technique in the finite element was used to observe the evolution of the thermal field during the deposition of a single-layer aluminum alloy, and the changes of the temperature field at different positions were analyzed.

摘要

(AFSD) Additive friction stir deposition is a novel solid-state forming method that can form isotropic material structures without solidification defects and the forming characteristics of the forming area and the forming thermal process in AFSD can significantly change the performance of the workpiece, therefore the thermal analysis of the forming process in AFSD is particularly important. The simulation of AFSD thermal process of AA6061-T6 aluminum alloy is missing. In this study, the cell life and death technique in the finite element was used to observe the evolution of the thermal field during the deposition of a single-layer aluminum alloy, and the changes of the temperature field at different positions were analyzed.
