چکیده مقاله
In this study, similar connection joint of AZ31 biodegradable magnesium alloy byfriction welding method was investigated Optical and electron microscopes SEM wereused to investigate the microstructure, X ray diffraction was used for phase analysis, andmicrohardness and tensile devices were used to investigate mechanical properties andpolarization tests were used to investigate corrosion resistance Welding was performedwith welding parameters of 1300 rpm, friction pressure of 50 MPa and forge pressure of40 MPa The microstructure results showed that the magnesium microstructure consistedof various regions such as near welding dynamic recrystallization DRX ,thermomechanical operation affected area TMAZ and partially deformed region Also,the tensile strength of the welded specimen was 243 1 MPa, which is equal to the tensilestrength of magnesium This is due to the formation of intermetallic compounds in thewelding region Suitable corrosion ofthe specimens is due to the formation of Mg17Al12intermetallic phase, because this phase is inert neutral chloride solution Hardnessvalues in the weld section were 135 5 Vickers, mainly due to grain refinement andMg17Al12 deposition in the weld
