摘要
Melt quality has a strong influence on all relevant properties of casting parts. For that reason melt quality attaches great importance. The aim of this study was to determine the existing melt quality in a foundry. Special emphasis was given to the influence of bifilms on melt quality and gas porosity formation. For this publication, the secondary alloy LM25 was chosen (AlSi7Mg0,5(Cu,Fe)). The melt quality was determined using reduced pressure test (RPT), porous disc filtration analysis (PoDFA), and fatigue and tensile testing techniques. The qualification of the RPT for evaluation of melt quality was examined. Furthermore, the RPT was developed into the advanced RPT. Based on the results of this study, suggestions for the measurement and moreover improvement of the melt quality have been proposed. © 2010, Springer-Verlag.
