چکیده
In the present scenario, aerospace and automobile industries depend on lightweight materials such as magnesium aluminum alloys because of their great balance between mechanical properties weight ratio. Despite these benefits during joining process dissimilar by welding, many challenges arises. The prominent one is related to low melting points metals which make it almost impossible using conventional arc welding techniques. To tackle this challenge, Friction Stir Welding (FSW) can be considered a promising candidate tool. study, demonstrate FSW performances two we have investigated AA 6061 Mg AZ 31 B built-in house modified milling machine. combinations joints were successfully joined embedding different conditions varying offset distance. evaluated conducting specific tests micro-hardness, tensile, impact tests, respectively. explain results, applied optical microscopy observation microstructure associated with bonding location. results prove that strength Welded much higher compared other techniques especially in terms metals.

A liquation cracking mechanism of dissimilar Al alloys during the friction stir welding (FSW) is suggested in this study. To identify the mechanism, the precipitates were analyzed and Al-Mg-Cu phase diagrams were calculated. Electron backscattering diffraction (EBSD) analysis and electron probe microanalysis (EPMA) were also conducted. In the same manner as constitutional liquation, at high hea...
