Band structure theory of the bcc to hcp Burgers distortion
The Burgers distortion is a two-stage transition between body centered cubic (BCC) and hexagonal close-packed (HCP) structures. Refractory metal elements from the Sc and Ti columns of the periodic…
Dislocation Induced FCC Twins at the HCP/FCC Interfaces in a Deformed Ti-5Al Alloy: Experiments and Simulations
This paper proposes a new formation route for the face-centered cubic (FCC) twins at the hexagonal close-packed (HCP)/FCC interface in a deformed Ti-5at.%Al alloy. From the experimental results, an…
Shifting the Shear Paradigm in the Crystallographic Models of Displacive Transformations in Metals and Alloys
Deformation twinning and martensitic transformations are characterized by the collective displacements of atoms, an orientation relationship, and specific morphologies. The current crystallographic…

TLDR
A new displacive model in line with previous work on martensitic transformations and extension twinning is proposed, which proves that the distortion is not a simple shear when it is considered in its continuity.
Twinning is not shearing: Case of the extension twins in magnesium
A crystallographic model is proposed for the extension twins in magnesium. It is based on a hard-sphere assumption previously used for martensitic transformations, and it reverses the approach of the…

TLDR
The crystallography of displacive/martensitic phase transformations can be described with three types of matrix: the lattice distortion matrix, the orientation relationship matrix and the correspondence matrix, and an explanation is offered of how to deduce the matrices of inverse transformation.
Over the shear paradigm
Deformation twinning and martensitic transformations are displacive transformations; they are defined by high speed collective displacements of the atoms, the existence of a parent/daughter…
