Study From CRISP selected as a 2015 Editors' Choice article

A study from Yale's Center for Research on Interface Structures and Phenomena (CRISP) has been selected as a 2015 Editors' Choice article for the Journal of Chemical Physics.

The paper, "On the origin of multi-component bulk metallic glasses: Atomic size mismatches and de-mixing," appeared on the cover of the journal's Aug. 7, 2015 issue. The study tested the conventional wisdom among researchers in the field that bulk metallic glasses (BMG) should contain three or more atomic species. The CRISP researchers performed computer simulations of ternary hard-sphere systems.

Among other results, the researchers found that when there are two components with a diameter ratio of less than 0.8, glass-forming abilities were enhanced by the addition of a third component  of intermediate size. This third component kept the other components from separating, also known as demixing.

The paper’s authors are Corey O'Hern, Jan Schroers, Kai Zhang, Yanhui Liu, Mark D. Shattuck, and Bradley Dice.
