Influence of Process Parameters on the Mechanical Enhancement of Copper-DHP by FSP
Friction Stir Processing (FSP) is an innovative solid-state processing technology, which is being currently used to enhance locally the mechanical properties of conventional materials. In this work, 1 and 3 mm-thick copper-DHP plates were processed with the aim of simulating surface (SFSP) and bulk (VFSP) processing. The influence of the processing conditions on the microstructure and mechanical properties of the processed materials was analyzed. It was found that the tool geometry, which has a close relation with the plastic deformation and dynamic recrystallization kinetics inside the stirred volume, the processing parameters and the heat exchange conditions, which determine the extent of dynamic recrystallization and annealing phenomenon, are determinant in FSP.
