Quantitative studies of gas porosity in cast aluminium & the determination of melt quality

Abstract:

Gas porosity is one of the major defects that forms during solidification in cast aluminium alloys. Hydrogen, oxide films, and TiB2 based grain refiner are all known to play a role in the formation of gas porosity, however their individual influences are not fully understood, necessitating further investigation.

In this work, metallography and low resolution X-Ray Computed Tomography (XCT), i.e. macro-CT, have been employed to study the effects of hydrogen, oxide...
