Abstract

A significant friction stir processed defect of kissing bond accompanied with coarse abnormal growth grains can be recognized where located aside the bottom of advancing side as raised up the rotating speed higher than 1450 rpm. Friction stir processed specimens not only possess refined α-Al phase, the coarse irregular solidification precipitates as breakup Al6(Mn,Fe) and Al6Mn actually could be refined and homogenized in stir zone result in a more stable strain hardening behavior especially from the initial stage of tensile deformation, abovementioned factors significantly benefit the tensile ductility of friction stir processed cast plate, but microstructural refinement did not cause apparent difference in yield strength and hardness performance that might result from the textural feature of friction stir processed fully annealed 5083 casting material.
