摘　　要：本文论述了超声波声速法检测铸铁件石墨组织的基本原理和方法,并使用超声波测速测厚仪对具有不同石墨组织铸铁件进行了检测,确定了不同石墨组织铸铁件与超声波声速的对应关系。应用超声波声速法可判断铸铁件材质种类,并能够实现对球化率和蠕化率水平的快速无损检测,具有显著的工程应用意义。Basic principle and method which using ultrasonic sound speed to test cast iron’s graphite structure was discussed in this paper.Test was conducted on cast iron with different graphite structure using ultrasonic speed and thickness apparatus,the rela-tionship between graphite structure and ultrasonic speed was determined.Ultrasonic method can judge types of cast iron and judge nodularity of cast iron rapidly without destroy,this method has remarkable engineering application significance.
