Abstract Scope |
Grain boundaries greatly influence many properties of engineering materials. Accurate prediction of their structure and possible transitions using atomistic modeling is important for strategies that aim to improve the properties of materials. Impurities and dopants are known to segregate to grain boundaries and can potentially have a significant impact on their structure and properties. In this study, we use a combination of atomic resolution scanning transmission electron microscopy (STEM) and atomistic modeling to investigate grain boundary phase transformations in metallic systems including those induced by solute segregation. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. |
