Magnesium (Mg) is used as a spheroidizer in_x000D_
the casting process. The amount of Mg in the melt determines the nodularity of the cast iron, which in turn determines the_x000D_
mechanical properties of the casting. The present process involves the addition of Mg to the molten steel in ladle, far upstream in_x000D_
the process. The challenge with this technique is that the Mg volatilizes from the ladle within a short period of time, thus, leading to_x000D_
lower nodularity from the beginning of the pour to the end hence, inferior mechanical properties of the casting. The current process_x000D_
of measuring the nodularity is through metallographic analysis by taking a sample from the ladle._x000D_
The proposed solution to this problem is to change the casting process in order to add Mg to the steel at the time that it is poured_x000D_
into the individual molds. A preliminary literature review has identified research that show the feasibility of a non-destructive test_x000D_
method that would provide faster results for determining nodularity of cast iron through the measurement of the acoustic speed of_x000D_
sound using ultrasonic sound waves. However, there is no data readily available for the type of casting alloy being used by Wabi_x000D_
Iron and Steel. This project proposes to use the pure research that has been done to develop a specific test method and_x000D_
experimental data that correlates the nondestructive measurements with actual metallographic condition of the material., program purpose french : Wabi Iron and Steel Corp. specialize in the design and development cast iron parts. Magnesium (Mg) is used as a spheroidizer in_x000D_
