Macro Porosity Formation: A Study in High Pressure Die Casting

Macro Porosity Formation: A Study in High Pressure Die Casting

David Blondheim Jr. & Alex Monroe Abstract Porosity formation in high pressure die casting (HPDC) impacts mechanical properties and casting quality. Much is published regarding micro porosity and its impact on mechanical properties, but there is limited research on the actual formation of macro porosity. In production applications, macro porosity plays a critically important role in casting
