The paper presents the analysis of the behavior of the cast aluminum alloy EN AW 5083 (AlMg4,5Mn0,7) to the friction stir processing (FSP), which is applied in order to locally modify some properties / characteristics of the base material. This method of metallic materials processing is currently an important research direction in the field of surface engineering. Some general data on the FSP processing and preliminary results obtained by ISIM Timisoara regarding FSP application on the cast aluminum alloy EN AW 5083 are presented. For the FSP processing experiments, three types of processing tools with different geometries, steel and tungsten sintered carbides, were used. The paper contains information on the development of the experimental program, data on FSP tools and technological parameters used, data on process monitoring using infrared thermography, as well as analysis and characterization of processed material. The obtained results about behavior to friction stir processing in a single pass of the cast aluminum alloy EN AW 5083 in correlation with the types of tools that are used, have been compared.
