Thermo-mechanical Study on TIG Welding of AA2024 Alloy and Subsequent Microstructural Events, M.Sc. Thesis Sharif University of Technology ; Serajzadeh, Siamak (Supervisor) ; Kokabi, Amir Hossein (Supervisor)
Abstract
In this study, temperature and Thermo-mechanical stress Distributions during and after TIG welding operations of AA2024 have been investigated by means of numerical simulation and experimental observations. Different geometries and initial microstructures, i.e. artificially and naturally aged alloys, have been selected. The model can determine the effect of welding parameters as well as mechanical fixtures on temperature and stress fields developed within metal being welded. Furthermore the subsequent aging behaviour of welded alloy (up to 70 days) has been evaluated employing hardness measurement and tensile testing. In addition, microstructural evolutions have been made utilising Scanning...
