Purpose: The goal of this paper is to present the thermal characteristics of magnesium alloy using the novel Universal Metallurgical Simulator and Analyzer Platform. Design/methodology/approach: The objective of this work is determine the liquidus, solidus temperature and beginning nucleation temperature to understanding crystallization of magnesium alloys. 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 hardness are shifting with an increasing cooling rate. Research limitations/implications: This paper presents results for one alloy. MCMgAl12Zn1 only, cooled with three different solidifications rate i.e. 0.6, 1.2 and 2,4 �°C/s, for assessment for the liquidus, solidus temperatures and describe a beginning of nucleation of �α(Mg)-β(Mg-Mg17Al12) eutectic and its influence on the mechanical properties. Further investigations should be concentrating on assessment an influence of different solidification rate on microstructure. 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.
