In this work, Al-7Si-0.3Mg alloy was studied. The alloy conditions was selected to be as-received, AlB3 grain refined and Sr modified. For each parameter, castings were made before and after degassing. In order to quantify ...

Hot tearing is one of the most interesting defects that can be found during casting of aluminium alloys. The definition of this defects has some uncertainties such as “it does not always appear under apparently identical ...
