Non-destructive method volume based on recording of back-scattered ultrasonic signal in from of A-scan was proposed for evaluation of diffused damage in metal. Informative technologies of processing of back-scattered signal and results of experimental testing on samples with different level of hydrogen damage were presented. Ref. 25, Figures 4
 
Keywords: diffused damage, ultrasonic back-scattered signals, statistical processing, dispersion, B-scan
