Role of defects in the thermodynamic stability of grain boundary phases at asymmetric tilt boundaries in copper
Swetha Pemma, Lena Langenohl, Saba Saood +5
Grain boundaries can exist as different grain boundary phases (also called complexions) with individual atomic structures. The thermodynamics of these defect phases in high-angle g…

Stable nanofacets in [111] tilt grain boundaries of face-centered cubic metals
Tobias Brink, Lena Langenohl, Swetha Pemma +2
Grain boundaries can dissociate into facets if that reduces their excess energy. This, however, introduces line defects at the facet junctions, which present a driving force to gro…
