摘要

得到了AlMn的亚稳二十面体相的熔解曲线T0和十面体相的液相线。%锰。二十面体AlMn在20℃时熔点为910±20℃。% Mn和熔点比具有相同组成的结晶化合物低约30°C。二十面体Al82Ru18在1260±30℃时熔化。这些结果是通过离子束混合形成单相二十面体合金，然后用电子束快速加热到精确的已知温度得到的。

Metastable phase boundaries of quasicrystalline phases

The melting curve T₀ of the metastable icosahedral phase and the liquidus of the decagonal phase of AlMn have been obtained for 14–22 at.% Mn. Icosahedral AlMn has a congruent melting point of 910±20°C at 20 at.% Mn and melts about 30°C lower than crystalline compounds with the same composition. Icosahedral Al₈₂Ru₁₈ was determined to melt at 1260±30°C. These results were obtained by forming single-phase icosahedral alloys with ion beam mixing and then rapidly heating to accurately known temperatures with electron beams.
