Because of the good sensibility, ultrasonic narrow band signal analysis technique with 1mhz central frequency was chosen to differentiate the heat treatment samples above - mentioned. there are obvious differences among heat treatment products in principal frequency, spectral peak ' s quantity, amplitude and distribution. that is to say, the technique of ultrasonic narrow band power spectral can be applied to characterize the microstructures of multi - phased alloy steels
利用窄帶信號頻譜分析技術靈敏度高的突出優點,選取中心頻率為1mhz的窄帶超聲信號,對上述不同熱處理試樣進行超聲功率譜分析,發現不同熱處理產物在功率譜主頻率、譜峰特徵(幅度、數量、分佈)等方面,都存在不同程度的差異。
