The principle of multi - method and multi - parameter is suggested, which should be followed during characterizing microstructures of alloy steels by ultrasonic not method. ultrasonic velocity ( c, ) of transformation products through different heat processes of three steels was measured by high - accuracy ultrasonic installation. the velocity of quenched microstructure of 38crmoal is the lowest, which gradually increases with increasing tempering temperature between 200 ? and 650 ? after quenching process
利用ti - 40n高精度超聲波測厚儀，研究了超聲波在不同鋼種、不同熱處理轉變產物中的超聲波速度c _ 1 : 38crmoal鋼淬火組織c _ 1最小，淬火后在200 650范圍內進行回火處理時，隨回火溫度的升高， c _ 1逐漸升高， hrc與c _ 1之間具有較好的相關性；正火組織的c _ 1介於淬火后中溫回火及高溫回火產物組織的c _ 1之間。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。
