 | Remigiusz Romankiewicz, Ferdynand Romankiewicz THE INFLUENCE OF MODIFICATION FOR STRUCTURE AND IMPACT RESISTANCE OF SILUMIN ALSI11 PRODUCTION ENGINEERING ARCHIVES 3/2(2014), pp. 6-9 DOI: 10.30657/pea.2014.03.02 | |
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. | ||
