| Abstract Scope |
The presence of liquid films at grain boundaries below the bulk melting
point can alter macroscopic properties of polycrystalline solids and
dramatically reduce their resistance to shear stresses. This talk will
discuss recent progress made in understanding grain boundary premelting using both atomic-scale and coarse-grained order parameter models. New fundamental insights that will be reported stem from detailed numerical surveys of those models over a wide range of parameters, analyses in tractable limits, and critical quantitative comparisons with molecular dynamics simulations in bcc and fcc elemental systems.
