Extended X-ray absorption fine structure (EXAFS) and molecular dynamic (MD) simulation were used to study the short-range order in Zr2Ni amorphous alloy. It is found that the bond length is significantly shorter for unlike atoms but longer for like atoms in amorphous state than that in the crystalline state. Meanwhile, the coordination number of Ni atom in amorphous structure is only half of that in ideal Zr2Ni crystalline. Based on these results, we proposed that there exists Zr2Ni-like chemical short-range order in the Zr2Ni amorphous alloy. (c) 2008 Elsevier B.V. All rights reserved.
