主要研究使用超声波探头对45钢不同组织进行检测,并对检测结果采用聚类分析的方法,将超声衰减系数和声速两个参量结合起来,寻求超声参量和微观组织间的对应关系,给使用超声参量来区分材料的微观组织提供理论和实验依据。 The main research uses the ultrasonic probe to test 45 steel different organizations, and uses the cluster analysis method to the test result, the ultrasonic decay coefficient and the sound speed two parameters combine, seeks the ultrasonic parameter and the microscopic correspondence between the organization, to use the ultrasonic Parameters to distinguish the microstructure of the material to provide theoretical and experimental basis.
