Structure and deformation characteristics in magnesium alloy ZK51A reinforced with AlN nanoparticles

The aim of this work was to study the influence of nanoparticles of aluminum nitride on the structure and mechanical properties of magnesium alloy. We examine the resulting magnesium alloys. The experiment consisted in the introduction into the melt of magnesium aluminum nitride powder in an amount of 0.75 and 1.5%. Introduction of nanoparticles into the molten metal was carried out by external vibration exposure. Studies were carried out of aluminum nitride powder, comprising X-ray diffraction analysis to study the morphology using electron microscopy. Introduction of nanoparticles in the alloy increases the pore volume space from 5 to 15% and increased average pore size from 8 to 30 µm. It was shown that the presence of the nanoparticles in an amount of 1.5% increases the alloy properties by more than 30% compared with the reference (non-particulate) alloy. We were obtained diagrams such as stress - strain. It was also carried out studies of the structure and X-ray analysis of the alloys obtained
