Effect of tool position on microstructural and mechanical properties of friction stir butt welded joint of AA2024–AA7075 dissimilar alloys
In this research, butt joining of Al2024 and Al7075 plates were performed by Friction Stir Welding (FSW) and the effect of tool position on microstructural and mechanical properties in about 1 mm from center line of joint towards the advancing side (AS) and the retreating side (RS) was investigated at three positions of +1, 0, -1 mm. In this regard, the plates of Al2024 and Al7075 were selected...
متن کاملEffect of Post-weld Heat Treatment on Joint Properties of Dissimilar Friction Stir Welded AA2024 and AA7075 Aluminum Alloys
In present study, the effect of heat treatment after friction stir welding dissimilar welds T6-7075 and T4-2024 aluminum alloys were investigated. Friction stir welding was performed at a constant rotation speed of 1140 rpm and welding speed 32 mm/min. After welding samples are taken under various heat treatment processes at different aging temperature and time period. Microstructural observati...
متن کاملNumerical Crack Growth Analysis in AA2024-T3 Friction Stir Welded Butt Joints
This paper deals with a numerical investigation on the influence of residual stresses on fatigue crack growth in AA2024-T3 friction stir welded butt joints. The computational approach is based on the coupled usage of the finite element method (FEM) and the dual boundary element method (DBEM), in order to take advantage of the main capabilities of the two methods. Linear elastic FE simulations a...
