EFFECT OF COOLING RATE AND GRAIN REFINEMENT ON THE MICROSEGREGATION IN Al-4.8 wt.% Cu ALLOY
Microsegregation is one of the most important phenomena occurs during solidification. It usually results in formation of some unexpected second phases which generally affect the mechanical properties and specially reduce the workability of casting products. The aim of this research is to study the effect of cooling rate and grain refinement on the microsegregation in Al-4.8 wt.% Cu. For this p...

EFFECT OF GRAIN REFINEMENT AND MODIFICATION OF EUTECTIC PHASE ON SHRINKAGE OF AlSi9Cu3 ALLOY
All metals and alloys with exception of Bi are shrinking during cooling, mostly during the solidification process. In order to avoid shrinking porosity, casting process, and gating and feeding system must be properly designed. Solidification front must move towards the feeding system where solidification is then completed. No separate liquid pockets where solidification ended without feeding sh...
