摘要
研究了圆片式3点弯曲法测量超硬材料的抗弯强度,以及超声波速率法和自由振动频率法两种方法测量超硬材料复合片的弹性模量,并对这两种方法做出对比。
The bending strength of superhard materials was measured by disk three point bending method in the paper,and elastic modulus of superhard materials composite waveplate were studied by using ultrasonic velocity method and free vibration frequency method,at last,the two methods were made a comparison.
