Thermal and structure analysis of the MA MgAl6Zn3 magnesium alloy

Purpose: This work presents effect of cooling rate structural properties and thermal characteristic results of MA MgAl6Zn3 cast alloy. Design/methodology/approach: The experiments were performed using the novel Universal Metallurgical Simulator and Analyzer Platform. Material used in this experiment is experimental magnesium alloy made as-cast. Findings: The research show that the thermal analysis carried out on UMSA Technology Platform is an efficient tool for collect and calculate thermal parameters. The formation temperatures of various thermal parameters and grain size are shifting with an increasing cooling rate. Research limitations/implications: This paper presents results for one alloy - MA MgAl6Zn3 only, cooled with three different solidifications rate i.e. 0.6, 1.2 and 2.4°C/s, for assessment for the liquidus, solidus and others temperatures and its influence on the structure. Practical implications: The parameters described can be applied in metal casting industry for selecting magnesium ingot preheating temperature for semi solid processing to achieve requirements properties. Originality/value: The paper contributes to better understanding and recognition an influence of different solidification condition on non-equilibrium thermal parameters of magnesium alloys.
