Abstract


In the present study, four alloys from diverse suppliers suitable for obtaining 413.0 metallurgical quality products together with alloy number 2 with an slightly hypoeutectic composition in Silicon were processed. The study focused on the microstructural characterization of the as-received ingots, as well as that of samples obtained from the production process: die cast samples and cold chamber pressure die cast samples. Finally a materials selection process base on microstructural grounds has been put forward as to determine the most suitable starting alloy for industrial production.
