Thermal and mechanical characteristics of cast Mg-Al-Zn alloy

This work presents effect of cooling rate on the grain size, mechanical properties and thermal characteristic results of MCMgAl9Zn1 cast alloy. The solidification process was studied using the cooling curve and crystallization curve at solidification rate ranging from 0.6°C/s up to 2.4°C/s. It was determined that the higher solidification rate increases the magnesium dendrite nucleation temperature. In addition, it was observed that the non-equilibrium solidus temperature and the grain size constituent decreases when the solidification rate increases.
