Viscosity of Metallic Glass Forming Liquids: Analysis Based on Bond Strength-Coordination Number Fluctuations Aniya, Masaru 103915 Ikeda, Masahiro 103916 安仁屋, 勝 103911 Ikeda, Masahiro 155894 池田, 昌弘 イケダ, マサヒロ 431 Viscosity Fragility Metallic Glass Forming Liquids Bond Strength-Coordination Number Fluctuation Model application/pdf 論文(Article) A model that describes the viscous behavior in terms of the mean values of the bond strength, the coordination number, and their fluctuations of the structural units that form the melt has been proposed by one of the authors. In the present study, the viscous behavior of several metallic glass forming systems are analyzed by using the model. From the analysis, microscopic information such as the number of bonds that must be broken to observe the viscous flow is obtained. It is also shown that when the magnitudes of energy and coordination number fluctuations are equal, the behavior of the viscosity described by our model corresponds perfectly to the behavior described by the Vogel-Fulcher-Tammann (VFT) equation. http://www.scientific.net/MSF.638-642.1621 journal article Trans Tech Publications 2010-01 AM application/pdf Materials Science Forum (Volumes 638 - 642) THERMEC 2009 1621 1626 AA10695957 https://kumadai.repo.nii.ac.jp/record/23665/files/Manuscript Mater Sci Forum 638-642 _2010_ 1621 _M.Aniya, M.Ikeda-r.pdf http://hdl.handle.net/2298/14749 https://kumadai.repo.nii.ac.jp/records/23665 jpn 02555476
