Structure and Crystallization Process of (Fe_l-xCr_x)₈₃B₁₇ Metallic Glass

The crystllization process of metallic glass (Fe_l-xCr_x)₈₃B₁₇ (x=0.05, 0.10,0.15, 0.25) was studied by differential thermal analysis, X-ray diffraction technology. Experiment proved the atomic bond force as an important driving force in the phase transition. The crystallization peak shifts towards high temperature with the increase in the concentration of high melting point Cr atom. The main structural unit of as-quenched state of (Fe_l-xCr_x)₈₃B₁₇ metallic glass contains atomic cluster of local nine-atom structure.
