Strontium As a Structure Modifier for Non-Binary Al-Si Alloy
Original language description
This paper presents a study of the influence on the structure of AlSi10Mg alloy when 400 ppm of strontium is added. Not only changes in the morphology of eutectic silicon, but in particular changes in the morphology of the intermetallic phases are monitored, namely phases containing iron and magnesium. The effect of strontium on structural defects, namely cavities formation, is also observed. It was found, that in non-binary system Al-Si-Mg also intermetallic phases of magnesium are affected by additionof strontium: especially phase Mg2Si changes the morphology significantly from unmodified to modified structure. Moreover, findings of other authors, that strontium has a negative effect on the level of gas porosity and on the distribution of shrinkages, are also confirmed.
