应用同步辐射X射线衍射(XRD)和广延X射线吸收精细结构边方法(EXAFS),结合反蒙特卡罗(RMC)拟合、Voronoi分形技术等对Zr50Cu50二元和Zr48Cu45Al7三元金属玻璃材料的微观结构进行了系统的研究.结果表明:ZrCuAl三元金属玻璃中Al原子与Zr原子、Cu原子之间存在强相互作用,表现为键长的明显缩短,导致其微观结构中的Voronoi团簇体积普遍小于Zr50Cu50,即前者的团簇内部原子更加密堆.这种原子密堆团簇可望从微观结构上解释CuZr体系掺Al后非晶形成能力大大提高的原因. The effects of X-ray diffraction (XRD) and extended side-beam X-ray absorption edge extraction (EXAFS) on the properties of Zr50Cu50 binary and Zr48Cu45Al7 ternary metallic glass materials were investigated by using inverse Monte Carlo (RMC) fitting and Voronoi fractal theory The results show that there is a strong interaction between Al atom, Zr atom and Cu atom in ZrCuAl ternary metallic glass, which shows the shortened bond length, which leads to the Voronoi cluster volume in its microstructure Which is generally less than that of Zr50Cu50, that is, the former is more densely packed with atoms inside the cluster. This close-packed cluster of atoms is expected to explain the reason why the amorphous formation ability of CuZr system is greatly improved from the microstructure.
