Abstract

The article deals with the possibility of applying acoustic methods for controlling the change in the physical and mechanical characteristics of long-life metal structures. Various methods for excitation and reception of ultrasonic waves are also given: impedance; laser-phase, coherent. Particular attention is paid to the coherent method, which, due to the rapid development of computer technology, allowed to create the modern information and measurement devices - failure detectors based on ultrasonic   field-induced phase grating (UFIPG). The advantages of UFIPG systems are shown including the possibility of their application to assess the change in the microstructure of metal structures material exploited under difficult conditions .
