| Abstract: | The various factors that affect the sound speed and the attenuation of sound wave of heavy section nodular cast iron are described in the article. It points out that the determination of the quality of heavy section nodular cast iron is that the sound speed and the attenuation of sound wave should be checked simultaneously at the stress condition. |
