Abstract

Twinning is a primary deformation mechanism in hcp metals and {

10 \bar{1} 2

} twins are prevalent in nearly every hcp metal. The 3D morphology and growth of twins is controlled by faceted structures at twin boundaries. We characterize the 3D faceted boundaries of {

10 \bar{1} 2

} twins in Ti using HR-TEM and compare them with Mg. We find eight characteristic facets in Ti, three of which were not observed in Mg. The revealed 3D facets provide the basic information for studying the kinetics, morphology, and transmission of the 3D twins and provide better understanding of differences in the deformation mechanisms of these materials.

期刊介绍： Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
