摘要
In the paper the microstructural phenomena in terms of average grain size occurring in friction stir welding (FSW) processes are focused. A neural network was linked to a finite element model (FEM) of the process to predict the average grain size values. The utilized net was trained starting from experimental data and numerical results of butt joints and then tested on further butt, lap and T-joints. The obtained results show the capability of the Al technique in conjunction with the FE tool to predict the final microstructure in the FSW joints. (C) 2009 Elsevier Ltd. All rights reserved.
