Abstract
Formation and microstructure of icosahedral quasicrystals in suction casting Al-6 at.%Mn(-2 at.%Be) alloys have been investigated by scanning electron microscopy, energy-dispersive spectrometer (EDS), x-ray diffraction (XRD), transmission electron microscopy, and differential scanning calorimetry (DSC). Based on the DSC analysis, isothermal annealing was designed, and XRD was performed to analyze the phase composition after heat treatment. The quasicrystalline microstructure of Al-6 at.%Mn(-2 at.%Be) alloys was obtained by suction casting. Be element addition in Al-Mn alloy modified the appearance of the quasicrystalline phases from hexagons to petals; meanwhile, the primary phase transformed from the Al6Mn compound to quasicrystalline approximant phase. Combined with XRD and scanning results show Be suppressed the formation of Al6Mn and promoted the formation of a quasicrystalline approximant phase. The thermal stability of the icosahedral phases contributes to a better performance of alloys at higher temperature. EDS analysis shows that the quasicrystalline phase is not a stoichiometric compound but a range of compositions.
