| Abstract: | The structures of microcrystalline AlSiMg alloys during heat treatment were studied using optical microscope Reichert MeF2 equipped with a monochrome TV camera VS-700. The average size of the silicon particles was determined. The significant influence of magnesium on the microstructure at high temperatures was demonstrated. Magnesium accelerates the structure coarsening process and a decrease of the effective activation energy of the silicon particles growth was found. |
