In this work, a finite-element model was elaborated to simulate the thermomechanical behavior of 6061 aluminum alloy during friction-stir welding (FSW). It shown that FSW-induced deformation is two-stage process. addition stirring action exerted by rotating tool probe, material in near-surface area stir zone also experienced secondary shoulder edge after passage tool. Both steps were found be comparable terms temperature and strain, but primarily concentrated layer. The effects rotation...
This work is part of a wide-ranging study aiming to enhance the technology dissimilar friction-stir welding aluminum and titanium. In previous study, new approach was proposed that provided an exceptionally narrow intermetallic layer. However, essential disadvantage this technique significant material softening in part. Hence, present undertaken order obtain insight into microstructural processes flow To end, stop-action applied. It found evolution included several stages. Specifically,...
The purpose of this study was to investigate the interfacial microstructure that produced during dissimilar friction stir lap welding (FSW) 6013 aluminum alloy and Ti-6Al-4V. FSW conducted under a zero-penetration condition, i.e., tool plunged exclusively into upper (aluminum) plate joint. To facilitate interpretation microstructural processes, finite element modeling (FEM) applied evaluate temperature field within weld zone. FEM simulation revealed very sharp gradient across interface. This...
The effect of strain and the friction on stress-strain state in deformation zone during cold rolling thin beryllium aluminum foils was investigated this work. Calculations showed that material hardening has a significant influence contact pressure distribution along arc. Although it, distributions hydrostatic stress triaxiality are favorable for fracture prevention both except narrow regions near entrance exit all considered cases (strain up to 40%, coefficient range 0.03 – 0.3). most is...
The relationship between the temperature conditions during friction-stir welding (FSW), stir-zone microstructure, and thermal stability of welded aluminum-alloy 6061 joints was established. To facilitate interpretation microstructural data, distributions generated FSW were quantified using a finite-element-modeling (FEM) approach. In all cases, microstructure found to be unstable against abnormal grain growth (AGG) post-weld solution annealing. Moreover, it that AGG always developed very...
