摘要

The formation of borides in an Al-3 wt.% B alloy produced from reaction between aluminium and boron oxide (B_2O_3) has been investigated. Melting and cooling experiments were carried out to explore the growth characteristics of aluminium boride crystals. During heating up tol300 ℃ boron dissolved into molten aluminium and subsequently cooled to form solid aluminium borides in the aluminium matrix. At room temperature boride particles was identified as AlB_2. Although, AIB12 phase is the first phase to form directly from the Al-B liquid above 1000 ℃ which transforms to stable AIB2 crystals by a peritectic reaction during cooling. Scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques were employed. Results showed that the shape and distribution of the borides are dependent on the cooling conditions of the liquid Al-B alloy.
