Quantification of volume deficit of rectangle shaped cast aluminium alloys
Source abstract
Abstract
Volume deficit of rectangular shape US 413 and US A356 cast aluminium alloy has been estimated in the present study. The decrease in specific volume directs to a volume deficit in castings and it has been shown as a defect. The volume deficit can be classified as macro cavities, internal porosity, surface sinking and volumetric contraction and measured using mathematical formulae; the actual volume deficit of the given casting was obtained by adding all the defects. Quantification of internal closed porosity has been addressed through X-ray computer tomography. The information regarding the volume deficit and its distribution is critical in minimizing casting defects.
