ACRC Research on Helium-Assisted Sand Casting Reported in Modern Casting
By MPI January 14, 2013
The December 2012 issue of Modern Casting reports on the ACRC research as published in the article Helium-Assisted Sand Casting which first appeared in the International Journal of Metalcasting. According to Metal Casting, research conducted by Dr. Muhammad Saleem and WPI and ACRC Prof. Makhlouf Makhlouf “investigates the possibility of using helium in sand casting to improve the rate of heat extraction from the casting and help expel the process-generated mold gases to achieve better secondary dendrite arm spacing (SDAS) in microstructure.” They concluded that “helium-assisted sand casting with a cross flow of helium increased porosity in the cast component and was deemed not viable. Helium-assisted casting with a parallel flow, however, showed improved tensile properties and reduced SDA by 23% compared to the baseline sand casting.”
