摘要：
The isothermal section of the Al-Si-B ternary system at 700 degrees C has been calculated using FactSage software and experimentally determined using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and x-ray powder diffraction(XRD). The calculated results show that there are six three-phase regions in the isothermal section: Liquid-Al+AlB2+(Si), AlB2+AlB12+(Si), (Si)+AlB12+SiB3, AlB12+SiB3+SiB6, AlB12+SiB6+SiB14, AlB12+SiB14+(B). Four three-phase regions of Liquid-Al+AlB2+(Si), AlB2+AlB12+(Si), (Si)+AlB12+SiB3 and AlB12+SiBn+(B) were confirmed experimentally, which are consistent with calculated results. The small AlB2 particles in the Al-3B alloy have good refining effect on the primary alpha-Al phase in the Al-10Si alloy, which greatly refines the microstructure and improves the mechanical properties of the Al-10Si alloy.
