分析从棒材圆柱面测定超声波衰减系数的方法 ,讨论在既定测试条件下 ,所测参量中非材质本身造成的声能损失情况 ,并对 4
The measuring method of the ultrasonic attenuation coefficients of cylinders was analyzed. Moreover, the ultrasonic attenuations which were not resulted from materials were studied under given conditions. The ultrasonic attenuation coefficients of 40Cr cylinders with different microstructures were analyzed and compared.
