Abstract

Porosity is detrimental to the mechanical properties of aluminium alloy castings, thus, in most of the cases, especially in structural parts, reduction of porosity is desired and pursued. Porosity can be caused by gas formation, solidification shrinkage, or non-metallic compound formation. In this work, the reduction of gas porosity formed by the hydrogen dissolved in the molten AlSi10Mg aluminium alloy has been studied employing an ultrasonic degasser in combination with purging gas blowing. Qualitative study of the hydrogen content of different samples has been performed employing the widespread reduced pressure test (RPT). Different factors affecting to RPT test have also been studied.
