摘要:Grain boundaries ( are the 2 D interfaces between crystals of the same material with different orientations Grain boundary behavior can be complex since their structure and properties depend on the relative orientation of the two crystals/grains and the inclination of the GB plane altogether a 5 dimensional space In this talk, Prof Srolovitz will particularly discuss the thermal roughening of GBs, the migration of GBs, GB shear coupling, and how GBs interact with applied stresses and compare these predictions with both molecular dynamics and experimental results.
