Change in Porosity of A356 by Holding Time and Its Effect on Mechanical Properties
In most of the practical casting operations, it is important to be able to cast large number of part with one single melt. Therefore, when quantity of the charge and melting crucible is increased, during casting process, ...
ON THE INTERPRETATION OF MELT QUALITY ASSESSMENT OF A356 ALUMINUM ALLOY BY THE REDUCED PRESSURE TEST: THE BIFILM INDEX AND ITS PHYSICAL MEANING
(Springer International Publishing Ag, 2018)
The oxide layer on liquid aluminum serves as a protective property to prevent the alloy from further oxidation. However, it has the potential to be a source of porosity when entrained into the bulk of the liquid. For this ...
Observation of Hot Tearing in Sr-B Modified A356 Alloy
(Polska Akad Nauk, Polish Acad Sciences, 2017)
In this work, T-shaped mould design was used to generate hot spot and the effect of Sr and B on the hot tearing susceptibility of A356 was investigated. The die temperature was kept at 250 degrees C and the pouring was ...
