Purpose: of this paper is to extend a complex evaluation of magnesium alloys which requires very often knowledge of structure and mechanical properties at elevated temperatures. These properties are connected with microstructure that is influenced by metallurgical and technological factors and exploitation conditions. Presented knowledge expresses very important information for design and exploitation of these alloys. Design/methodology/approach: The optical and scanning electron microscopy methods were used for metallographic and fracture analyses of studied magnesium alloys after tensile test at elevated temperatures. Findings: Objective of this work consisted in determination of structure and mechanical properties progressive magnesium alloys at elevated temperatures. Research limitations/implications: Knowledge of alloys structure characteristics will be determined new research direction of scope. Practical implications: The results may be utilized for a relation between structure and properties of the investigated material in process of manufacturing. Originality/value: These results contribute to complex evaluation of magnesium alloys properties namely for explanation of structure developed new magnesium alloys. The results of this paper are determined for research workers deal by development new exploitations of magnesium alloys.
