Most of the previous work was first explored in the context of crystal structures, which showed that atoms tend to arrange in certain patterns, or lattice arrangements, the most efficient of which are known as close-packed structures. These are modeled with a unit cell that is repeated in ...
The most efficient use of space however is obtained in the two close-packed structures, the face-centred cubic (fcc) and the hexagonal close-packed (hcp)
Design and processing of advanced lightweight structural alloys based on magnesium and titanium rely critically on a control over twinning that remains elusive to date and is dependent on an explicit understanding on the twinning nucleation mechanism in hexagonal close-packed (HCP) crystals. Here, by...
Configurations of close-packed clusters of substitutional point defects in crystalsdoi:10.1080/14786437508219962A theoretical study is described of the possible crystallographic configurations of small groups of either vacancies or solutes in which each point defect has at least one other point defect in ...
Within a tight binding framework, the interplay between local atomic arrangement, orbital directionality and phase stability properties is discussed for a series of tetrahedrally close packed (tcp) structures. The common features which characterize the local densities of states of tcp phases can be expl...

For close-packed crystal structures, SFs are formed as partial dislocations are nucleated and glide on the close-packed crystallographic planes. Different from full or complete dislocations, the glide of partial dislocations changes the local structure of the crystal, and hence, excess configuration ...
