Ultrasonic Velocity Measurements Used to Assess the

The Measurable Properties of material when being tested by ultrasonic methods are the velocity of the sound waves passing through the material and the loss of energy or attenuation of the sound in the material.Most modern techniques of testing for material quality are based on work published in 1957 by Ziegler and Gerstner.TheseUltrasonic Velocity Measurements Used to Assess the The Measurable Properties of material when being tested by ultrasonic methods are the velocity of the sound waves passing through the material and the loss of energy or attenuation of the sound in the material.Most modern techniques of testing for material quality are based on work published in 1957 by Ziegler and Gerstner.TheseUltrasonic Velocity Inspection to Ductile iron Material Ultrasonic Velocity Inspection to Ductile iron Material Quality and Nodularity. According to our experience,if the velocity is high,then the material and nodularity is good,otherwise,the material quality will be bad or unqualified.Higher than 5600 m/s,the rate of spheroidization will be higher than 90%,material is very good.
