By the x-ray diffractometry method, the authors found a change in the crystal structure of a number of metals in the zone of exposure of their surface to laser radiation with a flux density of 104–105 W/cm2. It has been shown that on exposure of the surface of metal samples to laser radiation, their crystal structure changes, in the exposed zone, from the equilibrium structure to a distorted one (having the shape of a parallelepiped, which is different from a cube). A relationship has been assumed between the disclosed effect and the occurrence of considerable microstresses in the zone of rapid anisotropic heating of metals.
