Sažetak
An influence of the melt treatment on the microstructure development and mechanical properties of the AlSi10Mg alloy has been established. Melt of the AlSi10Mg alloy has been treated by inoculant on the basis of Al-Ti-B composition with the aim of primary Al grains refinement, and by sodium salts to achieve modified fibrous morphology of eutectic silicon, Si. A microstructure development of the AlSi10Mg alloy was determined on the basis of phase analysis, and microstructural characteristics of the main constituents such as average surface area and the particles length in base, inoculated and modified melts related to the secondary dendrite arm spacing (SDAS). Correlated SDAS values and mechanical properties such as tensile strength and micro hardness indicate the efficiency of particular mode of melt treatment.
