| 英文摘要 | Local structure inheritance signatures were observed during the alloying process of the Ag50Sn50 melt, using high-temperature X-ray diffraction and ab initio molecular dynamics simulations. The coordination number N-m around Ag atom is similar in the alloy and in pure Ag melts (N-m similar to 10), while, during the alloying process, the local structure around Sn atoms rearranges. Sn-Sn covalent bonds were substituted by Ag-Sn chemical bonds, and the total coordination number around Sn increases by about 70% as compared with those in the pure Sn melt. Changes in the electronic structure of the alloy have been studied by Ag and Sn K-edge X-ray absorption spectroscopy, as well as by calculations of the partial density of states. We propose that a leading mechanism for local structure inheritance in Ag50Sn50 is due to s-p dehybridization of Sn and to the interplay between Sn-s and Ag-d electrons.
