چکیده انگلیسی
Experimental results on the structure and dynamics of metallic liquids and glasses are most frequently discussed in terms of phenomenological theories, such as the free-volume theory and the mode-coupling theory. However, the atomistic bases for these theories have been lacking. We propose a more fundamental, microscopic approach that may fill this gap. It is based upon the concept of fluctuating topology of atomic bonds described in terms of the atomic-level stresses. While this approach is still under development, it already has enabled quantitative description of some of the properties of metallic glasses, including glass transition, viscosity and glass formation.
