A brief review of the cryston concept and its applications is given. By definition, crystons are shear carriers arising in the contact interaction of dislocations with intersecting slip planes. The notion of standard orientations of habits (SOH) is introduced for shear bands. On the example of fcc crystals with SOH of the {hhℓ}-type, the conditions for generation and propagation of crystons, as well as for a discrete change of habit orientations, are considered. The reasons for deviations from SOH are indicated. With regard to the formation of martensite crystals, сrystons can act as dislocation nucleation centers, carriers of threshold deformation and relaxation shear. The areas of promising investigations are mentioned.
