Popis: | An investigation was conducted to find out the impact of the speed of rotation and pin profile of FSW tool on the microstructural characterisation & mechanical properties AZ80A magnesium alloy joints produced using FSW technique. FSW tools with completely three distinct pin profiles were at discrete speeds of rotation. The fabricated joints & their fracture surfaces obtained during tensile tests were subjected to microstructural & scanning electron microscopic (SEM) investigations. Comprehensive observations & investigational measurements were also carried out regarding the wear & hardness of the fabricated joints. The joints fabricated at 750 rpm using the taper cylindrical pin profiled tool exhibited high quality joints with better tensile strength, higher microhardness values and minimum wear. |
