摘要：

Results are presented of the chemical composition, qualitative and quantitative examinations of the test pieces' microzones and of the observations of transverse fractures surfaces of the modified casting magnesium alloys based on the EN-MCMgAl9Zn1 alloy. Presence of the following casting alloys main elements was confirmed in the analysed test pieces: magnesium, aluminium, manganese and zinc, constituting the structure of the a solid solution with the Mg17Al12 phases precipitations, as well as eutectics and phase AlMnFe, Mg2Si. Fractures of the investigated alloys were of a mixed nature. The investigation is carried out to testy the influence of the chemical composition and precipitation processes on the structure and mechanical properties of the magnesium cast alloys with different chemical composition in its as-cast alloys and after heat treatment.
