Provide a Modeling Algorithm for Mechanical Properties of Friction Stir Welding of 5 Series Aluminum and Pure-Copper Based on Fuzzy Logic

The copper/aluminum composite is very important and practical due to its light weight, optimal thermal electrical conductivity. high weight resistance ratio, along with inherent properties, makes it attractive for new applications. In this regard, the use of composites mechanical properties has significantly increased. research, 5000 series aluminum pure copper samples in 1st, 2nd, 3rd, 4th passes have been subjected friction stir welding (FSW) then metallurgical welded compared original samples. order further study results tensile tests, metallography microhardness tests performed. Microstructural evaluation showed that mixing zone was determined by combining layers. an increase yield strength ultimately improvement hardness ultimate weld prototype. Compared stretched samples, greater distance from nugget weld, less microhardness. By changing parameters increasing inlet temperature, uniform dispersion particles performed more appropriately increases strength. Finally, experimental data were modeled using fuzzy logic method considering presented model obtained two indices R-Sq (pred) (adj), 96 99%, respectively. comparison between indicated acceptable error data.
