Abstract

The presence of oxide films on the fracture surfaces of Al and Mg alloy test bars was examined using SEM. It was found that the films are unbounded, unwetted and double-sided in their nature. Oxide film defects were particularly clear in commercially pure Mg alloy. Computer simulation of filling of the mold and other metal transfer processes showed how the calculated free surface area of the liquid metal can be interpreted to show the potential for entrainment of the surface oxide film, suggesting how computer simulation can be quantitatively used in running system and casting process design.
