Porosity in Iron Castings from Mold-Metal Interface ...

Apr 01, 2000· In thinner sections, varying degrees of surface porosity or pockmarking were found. These defects probably were formed by gaseous decomposition products pushing away the semi-skinned-over casting surface. Since these bubbles are formed late in solidification at the mold-metal interface, there was not enough time for them to dissolve.
