The influence of modification for structure and impact resistance of silumin AlSi11
Journal Title: Production Engineering Archives - Year 2014, Vol 0, Issue 2
Abstract
In this paper the results of the modification process of alloy AlSi11 as well as the influence of modification for structure and im-pact resistance have been presented. The investigation revealed that the modification of the AlSi11 silumin with the addition 0,05 - 0,4% AlSr10 and 0,1 - 0,2% AlB4 simultaneously provided the advantageous refinement of the α-phase as well as the change of the morphology of the eutectic silicon from the lamellar into the fibrous one. The change resulted in a relevant increase in the impact resistance of the alloy and the widening of the plastic area of the fracture of the silumin samples.
