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…
Atomic resolution observations of silver segregation in a [111] tilt grain boundary in copper
Lena Langenohl, Tobias Brink, Gunther Richter +2
Alloying a material and hence segregating solutes to grain boundaries is one way to tailor a material to the demands of its application. Direct observation of solute segregation is…
Universality of grain boundary phases in fcc metals: Case study on high-angle [111] symmetric tilt grain boundaries
Tobias Brink, Lena Langenohl, Hanna Bishara +1
Grain boundaries often exhibit ordered atomic structures. Increasing amounts of evidence have been provided by transmission electron microscopy and atomistic computer simulations t…
