在铁基 Fe48Cr15Mo14C15B6Tm2 大块金属玻璃的结晶过程中发现了纳米级准晶结构态。类准晶结构与 χ-FeCrMo 结构相似，由于被视为 Mo 骨架的投影五边形排列而表现出变形的十倍衍射图案。我们展示了类准晶结构的初步结构模型，并讨论了基于 χ-FeCrMo 晶体近似的三维特征。
Nanoscale quasicrystal-like structural states have been found in the course of crystallization in an Fe-based Fe48Cr15Mo14C15B6Tm2bulk metallic glass. The quasicrystal-like structure is similar with the χ-FeCrMo structure exhibiting a deformed tenfold diffraction pattern due to projected pentagonal arrangements regarded as a Mo framework. We show the preliminary structural model for the quasicrystal-like structure and discuss the three-dimensional features based on the χ-FeCrMo crystalline approximant.
