Modeling and Characterization of Friction Stir Fabricated Coatings

The book presents a detailed three-dimensional mathematical model that elucidates heat generation mechanisms during friction stir fabrication. It examines how processing parameters influence the microstructure of samples, revealing that layer stratification and weld depth vary with these parameters. Optical microscopy and EBSD analysis, alongside Vickers microhardness measurements, indicate a consistent grain size within the weld nugget across different processing conditions. Additionally, it highlights how pressure and heat during the process affect the temper strengthening of strain-hardened Al5083 alloy.
