摘要：
Two kinds of sinters; made of reduced and atomized iron powders were identified by nonlinear ultrasonic measurement to detect higher harmonics generated at micro gaps comparable to the incident wave amplitude using PZT contact transducers of 5 MHz and 10 MHz. Furthermore, the advantage of the nonlinear ultrasonic measurement was demonstrated by the attenuation coefficient measurement for same samples.
