Abstract

Hardness and the microstructural variations were established in an AA 1050 series aluminum alloy subjected to friction stir weld. The design of the tool used consisted of a concave shoulder and threaded conical pin combination.  Sheets metals were perpendicularly cut; lamination direction 180 mm long and 80 mm wide with 5 mm thickness, they were joined in series of two sheets along by drawing 170 mm weld seams. From a small grains structure and a continuous network of fine particles in α-phase matrix with equiaxial grains, after welding, the affected thermo-mechanical zone shows a reorientation, with some recrystallization degree and the presence of re-precipitated eutectic silicon particles in the affected thermal zone.
