چکیده انگلیسی
Friction stir processing (FSP) has demonstrated to refine the microstructure of different alloys resulting in superior mechanical properties. Abnormal grain growth (AGG) has been recognized as a critical issue during hot deformation of FSPed Al alloys. 5083 Al alloys with different Mn content were subjected to heat treatments at 350 and 535 °C before FSP to avoid AGG during subsequent hot deformation. As a result, heat treatment of 350 °C was able to retard AGG significantly. Also, an improvement in the refinement of the microstructure was observed. Consequently, a better ductility of 861% at elevated temperature was reached in the alloy with lower Mn content comparing with the same alloy without heat treatment prior to FSP.
