Abstract

Faceting and migration of twin tips in slightly deformed Zn [112̅0] flat single crystals have been investigated. The stationary shape of the slowly migrating tip of the twin plate has been studied, and the migration rate has been measured between 592 and 692 K in situ using polarized light. Below 632 and above 682 K, the twin tip contains only one facet which is parallel to the (1̅102̅)2 and (11̅00)1 plane of the matrix single crystal, respectively. The non-physically high values of the apparent migration activation enthalpy between 632 and 682 K are discussed using the model of simultaneous migration of co-existing grain boundary facets based on the concept of weighted mean curvature. The experimentally determined temperature dependence of the twin tip mobility can be rationalized under the assumption that the migration of individual facets is characterized by identical activation enthalpies of 46.6 kJ/mol, but different pre-exponential factors (1.1×10–11 and 7×10–9m2/s, respectively).
