| Abstract: | In this paper, the authors describe the experimental research on the ultra-sonic longitudinal and shear wave velocity and attenuation of the tightening screw in Qinsan 300, 000 kilowatt nuclear power plant. Meanwhile, the coupling layer correction and diffraction correction have been made. The experimental results show that the lower alloy steel with high strength used for the tightening screw in nuclear power plant possesses lower attenuation property of ultrasonic wave. Its ultrasonic wave velocity is less than common carbon steel. The results show that this material is an ideal medium for ultrasonic testing. |
