According to structural characteristics of multi - phased alloy steels and the properties of ultrasonic propagation, microstructures characterization with different heat treatment processes ( normalizing, quenching / annealing, quenching plus low tempering, quenching plus high tempering ) for three steels ( 40cr, 38crmoal, gcrlssimn ) was studied experimentally by using ultrasonic methods. ultrasonic velocity, relative attenuation coefficient, and power spectral analyses were researched on the same samples respectively, on the basis of theory and experiment, the sensitivity and other characterizations of the three methods used to distinguish different microstructures were compared
根據具有多種相結構合金鋼不同熱處理轉變產物的組織特點，以及超聲波在其中的傳播規律，利用超聲波速度、相對衰減系數以及功率譜分析三種方法，對三種鋼（ 40cr 、 38crmoal及gcr15simn ）不同熱處理（正火、淬火退火、淬火+低溫回火及淬火+高溫回火）轉變產物的顯微組織進行了超聲表徵研究。
