Effect of cooling rate on the solidification behavior of MC MgAl6Zn1 alloy

In this work effect of cooling rate on thermal characteristic results of MC MgAl6Zn1 cast alloy have been described. The solidification process was studied using the cooling curve and crystallization curve at solidification rate ranging from 0.6 degree C/s up to 2.4 degree C/s. It was determined that the higher solidification rate decreases the solidus temperature. In addition, it was observed that the beginning of nucleation of alpha(Mg)-betha(Mg-Mg17Al12) eutectic temperature constituent increases when the solidification rate increases.
