CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn the paper the Friction Welding (FRW) process is investigated by means of FEM simulation and experimental trials on AA 6082-T6 round extruded bars. Tests are realized at different rotational speeds and forging forces: the thermal field is monitored by means of k-type contact thermocouples and a contactless self-calibrating pyrometer. Deform lagrangian code is initially validated and optimized for process simulation of experimental trials then the simulations were used for the analysis of welding quality (through welding criteria) and for the microstructure evolution by means of a model already developed by the authors for aluminum extrusion microstructure evolution prediction.
