EVALUATION OF THE EFFECT OF MECHANOSYNTHESIS PARAMETERS ON THE MORPHOLOGY OF A MAGNESIUM-BASED POWDER COMPOSITION

This article presents an analysis of the dependence of phase and morphological changes in the powder composition of the Mg-Ni-Ce system on the parameters of mechanical synthesis. During the mechanical synthesis process, it was found that, in addition to acceleration and duration parameters, the ratio of powder to milling balls has a significant influence on changes in the structural characteristics of the material. The results of the microscopic analysis showed that with a powderto-ball ratio of 1:10, the average particle size in the synthesized mixtures is 13.76 µm. At the same time, when applying a ratio of 1:30, the particle size decreases to 7.59 µm. It was established that magnesium is the primary phase in all samples. However, at a ratio of 1:30, the formation of the hexagonal crystal lattice of the MgNi phase and the emergence of the CeNi phase are identified.
