New approach to the technology of ultrasonic testing of coarse-grained materials

摘要

The paper describes the solution of the problem of construction of an acousto-solidification model of coarse-grained materials, allowing for the features of structure formation, geometrical and energy factors of ultrasonic (US) waves attenuation. Analytical dependencies were derived, a program was made and some results are given of calculation of the passage and scattering of all types of US waves. A conclusion is made on the need to take into account the actual geometry and energy of the US beam for a correct interpretation of the results of UT of the objects from materials of the above type.
