The reason for anisotropy in material properties is the thermo mechanical effect in the process of plastic deformation, which creates a texture along the direction of deformation. One of the established nondestructive methods for evaluating the elastic constants in anisotropic materials is by measuring the velocities of ultrasonic waves propagating in different directions in the material. For studying the elastic anisotropy of textured media, the established measurement methods are hardly applicable because the materials are inaccessible for volumetric measurements. Moreover, the differences in the velocities of the ultrasonic waves are very small and the changes are localized in the surface and subsurface layers. The purpose of the study is to test a methodology and carry out the experimental studies to determine the anisotropy parameters of metallic materials based on the data from changes in the velocity of ultrasonic waves.
