| Abstract Scope |
Previous works have shown that GB mobility and interactions with other defects greatly influence the properties of polycrystalline materials. In this work, molecular dynamics simulations are utilized to explore the mobility and interaction of a migrating GB with interstitial Frank loops, using a set of equilibrium and non-equilibrium GBs along the [100] tilt axis in Cu and Ni-Cr systems. Our results show that the mobility and interaction of GBs are directly related to their structures. For Cu, the GB mobility decreases with a higher density of B structural unit, while the sink efficiency of a GB, namely, the capability of a GB to absorb the Frank loops, increases. For Ni-Cr, both GB mobility and sink efficiency decrease with increasing solute concentration. Importantly, this effect is more apparent for GBs with higher densities of B structural units. Finally, these properties can also be altered by varying the local GB structure. |
