“…56. The above observations and conclusions in Cu-Zr are in good agreement with prior simulations conducted by Falk and co-workers [340,385,386,388,390]. These results also corroborate the strong configurational dependence of shear modulus observed in both experiments and simulations [396,[416][417][418].…”

“…The interplay of SRO and mechanical behaviors in model glasses has been systematically studied by Falk and co-workers [79,340,[385][386][387][388][389][390]. For example, in the unstable and energetic shear band, they found depletion of SRO, as shown in Fig.…”

“…The effects of processing history on the structure and mechanical properties have been studied by Falk and co-workers in 2-D and 3-D model glasses [340,[385][386][387][388][389][390]. Specifically, by quenching the sample from different initial temperature, or at different cooling rates, different degree of structural ordering and percolation of the ordered clusters can be produced.…”

“…Molecular dynamics ͑MD͒ simulations have been successfully performed to analyze the structural, thermodynamic, and dynamic properties and to investigate the glass forming mechanism of simple Cu-Y, Ni-Zr, Cu-Ag, Cu-Ni, Ni-Mo, Be-Zr, Ni-Zr-Al, Cu-W, Fe-C ͑B, P͒, and Cu-Mg amorphous alloys [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] at a microscopic level on a scale ranging from the vibration to the mesoscopic times. However, most of these simple binary alloys mentioned above, which showed good glass forming abilities in simulation processes, cannot be fabricated into bulk amorphous samples experimentally.…”

We have identified a binary bulk metallic glass forming alloy Cu 46 Zr 54 by analyzing the structure and thermal behaviors of copper mold cast samples using x-ray diffraction, transmission electron microscopy, and differential scanning calorimeter. Motivated by these experimental results, we fitted the effective RosatoGuillope-Legrand-type force field parameters for the binary Cu-Zr alloy system and the atomistic description of glass formation and structure analysis of the Cu 46 Zr 54 alloy based on molecular dynamics simulation will be also presented.

“…The full implications of the structural information acquired so far for atomic diffusion and plastic flow remain to be elaborated. How the structures transform upon changes in thermodynamic and processing variables, 13 or under deformation, [14][15][16] is only beginning to be investigated. It also seems that our current understanding of metallic glass structures does not yet enable predictions of their stability.…”

Glassy alloys (metallic glasses) are currently the focus of intense research in the international metals community. Setting aside elevated-temperature applications, these amorphous metals have exciting potential for structural applications. When metallic glasses were first widely studied in the 1960s, the alloy compositions then known to be quenchable into the glassy state from the liquid required high cooling rates on the order of 10 6 K s −1 and were consequently restricted to thin sections. The current interest in metallic glasses has its origin mainly in the increasing range of compositions that can now be cast into glasses at much lower cooling rates, permitting minimum sections of 1 mm to 1 cm or even larger. These bulk metallic glasses (BMGs) are the focus of the articles in this issue of MRS Bulletin. Our goal is to illustrate the major materials issues for BMGs, from processing to structures to properties and from the fundamental science of glasses to viable industrial applications. We hope that the articles, in providing a snapshot of a rapidly moving field, show why BMGs are attracting such intense interest and serve to highlight some challenging issues awaiting resolution.
