Abstract

Nanoscale quasicrystal-like structural states have been found in the course of crystallization in an Fe-based Fe₄₈Cr₁₅Mo ₁₄C₁₅B₆Tm₂ bulk 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.
