Purpose: The goal of this paper is to present the new methodology to determine the thermal characteristics of magnesium alloy using the novel Universal Metallurgical Simulator and Analyzer Platform. 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 are shifting with an increasing cooling rate. Research limitations/implications: This paper presents results for one alloy . MCMgAl9Zn1 only cooled with two different solidifications rate i.e. 0.6 and 2°C/s, for assessment for the liquidus, solidus temperatures and describe a beginning of nucleation of α(Mg)-β(Mg-Mg17Al12) eutectic. Further investigations should be concentrating on assessment an influence of different solidification rate on microstructure and mechanical properties. Practical implications: The parameters described can be applied in metal casting industry for selecting magnesium ingot preheating temperature for semi solid processing. Originality/value: The paper contributes to better understanding and recognition an influence of different solidification condition on non-equilibrium thermal parameters of magnesium alloys.
