Influence of cooling rate on crystallization, structure and mechanical properties of MCMgAl6Zn1 alloy

This work presents an influence of cooling rate on crystallization process, structure and mechanical properties of MCMgAl6Zn1 castmagnesium alloy. The experiments were performed using the novel Universal Metallurgical Simulator and Analyzer Platform. Theapparatus enabled recording the temperature during refrigerate magnesium alloy with three different cooling rates, i.e. 0.6, 1.2 and2.4°C/s and calculate a first derivative. Based on first derivative results, nucleation temperature, beginning of nucleation of eutecticand solidus temperature were described. It was fund that the formation temperatures of various thermal parameters, mechanicalproperties (hardness and ultimate compressive strength) and grain size are shifting with an increasing cooling rate.
