Abstract

The work includes the description of fatigue cracks testing. The first tests were carried out with the help of microwave crack detector using the ultrasonic sound. The tests results proved the expectation. The equipment set “Remote Indicators Active Defects-2” (also RIAD-2) allows to perform remote detection of the active defects, occurring in the metal parts of the samples after cycle testing. The aftereffect with the duration time starting from several minutes and up to several hours was pinpointed for the first time. The successful results were achieved in the reactivation of inactive defects.
