                         combination of dissimilar materials have applications in several 
                         areas of engineering, from automotive to aerospace. Its use 
                         facilitates the assembly and development of projects, contributes 
                         to reducing the mass of space systems and project costs. In the 
                         rotational friction welding process (RFW), the heat generated at 
                         the interface is the result of the transformation of mechanical 
                         energy into thermal energy, resulting in mechanical deformation 
                         and atomic interdiffusion between the materials involved in the 
                         process, producing dissimilar joints with structural quality. The 
                         main objective of this work is the microstructural 
                         characterization through Optical Microscopy and Scanning Electron 
                         Microscopy (SEM), of the connection interface of dissimilar 
                         aluminum AA1050 and AISI 304 stainless steel joints, joined by the 
                         process of RFW. The analyzes performed showed that there is 
                         interdiffusion between the main alloying elements of the materials 
                         involved in the process, formation of layers of intermetallic 
                         compounds with different thicknesses, presence of alloying 
                         elements in different regions of the fractured surfaces, and 
                         failures in,. the diffusion on the surfaces of contact. Results of 
                         the analyzes were correlated with mechanical strength of the 
                         joints and parameters used in the process, demonstrating that the 
                         thickness of the layers of intermetallic compounds and the 
                         presence of the Fe on the surfaces are directly related to the 
                         mechanical strength and affecting the quality of the joints
