Abstract
For setting up innovative processing technologies, such as semi-solid casting, a fundamental contribution can be offered by numerical simulation, which, once correctly elaborated, allows the prediction of fluid-dynamics and thermal fields induced by the process. This paper is focussed on the study, by means of the MAGMAthixo module of the MAGMASOFT code, of the semi-solid casting process of an automotive component (engine bracket). The requirements for a proper development of the numerical model are described and the results of simulation are presented as mass and temperature distributions and compared with the output of experimental processing tests and with microstructural investigations. The good correspondence between experimental data and numerical simulation results confirms the reliability of this approach in developing processes and products.Pubblicazioni consigliate
