Analysis of the Evolution of Mechanical Properties of Metallic Materials by AMD-Methods for Thermomechanical Impacts

One of the topical material science problems today is the problem of analyzing the evolution of the mechanical properties of metallic materials, predicting their behavior under thermomechanical influences. To solve this problem, it is suggested to use methods of acoustomicrouscopy flaw detection or AMD-methods [1]. They make it possible to obtain, with the aid of acoustic waves (AB), images of the structure at various depths from the surface of the object. This does not require any additional surface treatment, including chemical etching. The advantages of analyzing the evolution of the mechanical properties of alloys using AMD methods are related to the fact that acoustic waves and their characteristics are sensitive both to the parameters of the structural elements and to their changes associated with external influences.
