The role of SiC and TiC nanoparticle reinforcement on AA5083-H111 friction stir welds studied by electron microscopy and mechanical testing

摘要

AbstractFriction stir welding is an innovative method that can have a lot of industrial applications. In the following study, the influence that SiC and TiC nanoparticle reinforcement has in the microstructure and the mechanical properties of the weld nugget of thin AA5083-H111 welds is going to be determined via optical and electron microscopies as well as mechanical properties and microhardness testing. A research is provided over the dislocation distribution as well as the intermetallic particles that appear in the weld nugget of the reinforced as well as the unreinforced welds. Finally, the mechanisms governing the process are presented and commented.]]>
