Simulations, modeling, and designs of bulk metallic glasses (2007)
Bulk metallic glasses usually have very high yield strength, at least double that of ordinary commercially used crystalline materials, and high elastic strain limit, roughly 2% in tension or...

Thermal and elastic properties of Cu–Zr–Be bulk metallic glass forming alloys (2007)
Duan, Gang, Lind, Mary Laura, De Blauwe, Katrien, Wiest, Aaron, Johnson, William L.
The compositional dependence of thermal and elastic properties of Cu–Zr–Be ternary bulk metallic glass forming alloys was systematically studied. There exists a linear relationship between the...
Strong configurational dependence of elastic properties for a binary model metallic glass (2006)
Duan, Gang, Lind, Mary Laura, Demetriou, Marios D., Johnson, William L., Çağin, Tahir, ...
In this work, the strong dependence of elastic properties on configurational changes in a Cu–Zr binary metallic glass assessed by molecular dynamics simulations is reported. By directly evaluating...
Cooperative Shear Model for the Rheology of Glass-Forming Metallic Liquids (2006)
Demetriou, Marios D., Harmon, John S., Tao, Min, Duan, Gang, Samwer, Konrad, Johnson, William L.
A rheological law based on the concept of cooperatively sheared flow zones is presented, in which the effective thermodynamic state variable controlling flow is identified to be the...
