Abstract :
This study presents the research results of effect that refining process has on porosity and mechanical
properties of high pressure die castings made of AlSi12S alloy. The operation of refining was carried out in a melting
furnace with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were
assessed on samples taken from high pressure die castings. The effect of molten metal transfer operation and the time
elapsing from completion of the refining process on the alloy mechanical properties was determined.
