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高精度超声波测厚仪，研究了超声波在不同钢种、不同热处理转变产物中的超声波速度c _ 1 : 38crmoal钢淬火组织c _ 1最小，淬火后在200 650范围内进行回火处理时，随回火温度的升高， c _ 1逐渐升高， hrc与c _ 1之间具有较好的相关性；正火组织的c _ 1介于淬火后中温回火及高温回火产物组织的c _ 1之间。
