An ultrasonic method for quantitative evaluation of the metal structure of axles of wheel pairs
Source abstract
Abstract
The number of operating frequencies of ultrasonic vibrations necessary for evaluating the granularity of metal is determined. An ultrasonic technique for evaluating the granularity of the metal of axles of wheel pairs is proposed taking into account both the influence of the cylindrical surfaces of injection and reflection of ultrasound and the roughness of the axle surfaces. The coefficient of anisotropy of the metal of axles has been experimentally determined and the coefficient of anisotropy of hypoeutectoid steels has been calculated as a function of the ratio of structural components. The results of experimental studies are presented.
