Temperature interval determination for the performing local squeezing casting process on the AlSi10Mg alloy castings

摘要

The temperature interval for the performing local squeezing casting process has been established with the aim of the hot spot elimination, i.e. potential place of the shrinkage cavity occuring in the AlSi10Mg alloy casting. The local squeezing process temperature has been determined on the base of preliminary examinations of the AlSi10Mg alloy, whereby the temperature intervals and the relevant temperature of the significant phase precipitations have been established, as well as prediction of the place of shrinkage cavity occurrence based on the numerical simulation of the pouring and casting solidification. The influence of variation of process temperature on the density, i.e. soundness (compactness) of AlSi10Mg alloy castings has resulted in temperature interval determination.
