Grain boundaries and interfaces in slip transfer
The effect of slip transfer on heterogeneous deformation of polycrystals has been a topic of
recurring interest, as this process can either lead to the nucleation of damage, or prevent …

Enhanced strength in pure Ti via design of alternating coarse-and fine-grain layers
The yield strength of metals is typically governed by the average grain size through the Hall-
Petch relation, and it usually follows the rule of mixture (ROM) for layered composite …

Disconnections and other defects associated with twin interfaces
The general topological model for interfacial defects is reviewed and expanded, and the role
of these defects in the coupled shear-migration of interfaces is explored. We focus on …
