本文叙述了用超声频谱技术对Ti-6Al-4V合金的冶金结构所进行的试验。试验结果表明,宏观晶粒的尺寸与超声衰减的大小之间并无直接联系,而显微结构的差异是有可能用超声频谱曲线的不同加以表征的。
This paper describes the use of ultrasonic spectroscopy Ti-6Al-4V alloy metallurgical structure of the test carried out. The experimental results show that there is no direct relationship between the size of the macroscopic grains and the size of the ultrasonic attenuation, and the difference of the microstructures may be characterized by the difference of the ultrasonic spectrum curves.
