Use of barbotage refining of aluminumsilicon alloy to improve mechanical properties of high pressure die castings
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
This study presents the research results of the influence that barbotage refining on the mechanical properties of high pressure die casting made of AlSi12S alloy. The operation of refining was conducted in a melting furnace, with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were assessed on the samples taken from high pressure die castings. The influence of transferring molten metal and the influence of time of keeping molten metal undergoing the refining process on the alloy mechanical properties.
