Use of controlled gassing of Al-Si alloys during die casting
Jankes, Erik ; Kaňa, Václav (referee) ; Roučka, Jaromír (advisor)
This master thesis will cover the possibility of using directed gassing of Al-Si alloys in a high pressure die casting foundry. As a control gas, rotary degasser with gaseous 20 % H2 in N2 as a medium was used. Castings were casted via high pressure die casting machine. The aim of this research is to compare internal defect such as porosity or shrinkage of a casts made from degassed and control gassed melt.
