| contents | Effects of shoulder geometry of tool on microstructure and mechanical properties of friction stir welded joints of AA1100 aluminum alloy Jimy Unfried-Silgado Alexander Torres-Ardila Juan Carlos Carrasco-García Johnnatan Rodríguez-Fernández Ingeniería tools microstructure aluminum alloys Friction Stir Welding mechanical properties In this work were studied the effects of shoulder geometry of tool on microstructure evolution and mechanical properties of friction stir welded joints of AA1100 aluminum alloy using a milling machine. Three designs of shoulder geometry were evaluated with the aim to induce different distributions of thermal cycles in welding regions. Thermal cycles were measured using thermocouples and a data system acquisition. A microstructural characterization and crystallographic analysis of the welded regions were carried out using optical, scanning electron microscopy, and electron backscattering diffraction. The mechanical properties were measured by transverse tension, guided bend and hardness tests. The weldability behavior was established based on the experimental data. Results showed that the features shoulder tools produced an important effect on the thermal cycles, generating a plasticized wide region and biggest grain size in stir zone when compared with flat shoulder tool. 2017 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49650910024 https://www.redalyc.org/journal/496/49650910024/ https://www.redalyc.org/journal/496/49650910024/html/ https://www.redalyc.org/journal/496/49650910024/49650910024.epub https://www.redalyc.org/journal/496/49650910024/movil en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.200 Vol.84 |
