The solidification during flow of composite suspension in the permanent mould
Journal Title: Archiwum Odlewnictwa - Year 2011, Vol 11, Issue 2
Abstract
The presented work presents the influence of graphite particles on the solidification kinetics of metal suspension based on AlSi10Mg alloy during the die cavity filling. In order to examine this problem, the measurements concerning temperature changes in the selected points of the metal mould have been taken for two materials poured into the die: the pure AlSi10Mg alloy and the alloy reinforced with graphite particles. Thus the solidification and cooling curves of the examined material have been achieved. The recorded temperature changes have served as a basis for preparing graphs representing the velocity of the metal stream and the distance travelled by the front of the stream against the time. The introduction of graphite particles into the matrix alloy has caused the shortening of the distance flown by the material by 50% as compared with the non-reinforced alloy. The recorded temperature changes have allowed also for determining the temperature changes for the front of the metal stream during the die filling. Taking into account these results it has been found that the AlSi10Mg+10%Cgr composite begins its solidification after having covered the distance seven times shorter than the corresponding distance measured for the non-reinforced AlSi10Mg alloy.
