Friction stir welding (FSW) is a promising welding process that can join age hardenable aluminium alloys with high joint efficiency. However. the thermal cycles experienced by the material to be joined during FSW resulted in the deterioration of mechanical properties due to the coarsening and dissolution of strengthening precipitates in the thermo-mechanical affected zone (TMAZ) and h... https://jalyttlers.shop/product-category/pillows/
