producing of composite layer of SiC/Al5083 via friction stir processing

friction stir processing is a solid state process to modify microstructure and mechanical properties of sheet metals and as-cast material in this process stirring action of the tool causes the material to intense plastic deformation that yields a dynamical recrystallization in this study the effect of FSP and process parameters on hardness and microstructure of AL5083 has been investigated also by using of FSP composite layer of SiC/AL5083 has been produced results show that FSP leads to finer and homogenized grain structure as well as increased hardness. the composites produced by FSP have uniformly distribution of SiC particles between the grains of base metal.
