- Title
Degradation and Fracture of Crystals of Gallium and Indium Selenides.

- Abstract
In the Laue patterns of crystals of gallium selenide, we experimentally established the blurring of diffraction spots in the radial direction (asterism). The elongation of tails depends on the number, shape, and dimensions of fragments. The isomorphic substitution of elements results in the appearance of GaxIn1 - xSe and (In0.6Ga0.4)2Se3 solid solutions. In the course of deformation and fracture of mixed (In0.6Ga0.4)2Se3 crystals, slip bands reach the surface due to mechanical stresses. The spalling of crystals occurs at an angle about 45° to the direction of applied tensile stresses. Brittle fracture of the alloy is accompanied by the simultaneous disintegration of a crystal at several sites.
