... ) nanocomposites with nanosized SiC particles placed either in microsized Si 3 N 4 grains or along Si 3 N 4 grain boundaries (GBs). This work focuses on analyzing the influence of GBs, interfaces, and impurities on thermal and mechanical properties of a set of SiC – Si 3 N 4 nanocomposites at three different...

... structure on material properties. Future directions in grain boundary modeling are discussed, including studies focused on the role of grain boundary impurities and issues related to linking grain boundary mechanisms observed via atomistic simulation with continuum models of grain boundary plasticity...
