摘要：The most commonly used method for detecting hydrogen damage is ultrasound. Ultrasonic testing through the detection of ultrasonic wave changes in metal materials to know the location of material defects and the change of wave velocity, and then get the material mechanical properties of the change. This chapter mainly uses the method of ultrasonic detection to detect the change of ultrasonic wave form and the change of wave velocity of 2.25Cr1Mo0.25V steel base metal and weld under different hydrogen charging time, so as to obtain the change of elastic modulus of the material. ? 2021 IEEE.
