Abstract |
The crystallographic sites available for the point defects in the unit cells of the Ti-Ni, Au-Cd, Heusler
alloys and vanadium crystals have been considered. Two different effects have been analyzed: i) spatial redistribution
of point defects during the ferroelastic phase transitions (such as martensitic transformations
in the Ti-Ni, Au-Cd and Heusler alloys); ii) deformation of crystal lattice caused by the hydrogen ordering
in the course of hydrogen absorption in vanadium. The configurational order parameters describing the
spatial symmetry of defect or hydrogen system have been constructed from the probabilities of crystallographic
sites occupation by the defects or hydrogen atoms, respectively. |
