Increasing the precision of measurements of the velocity of acoustic vibrations in ultrasonic analysis of cast-iron articles

  • Acoustic Measurements
  • Published:
Measurement Techniques Aims and scope

The article considers a method of ultrasonic structural analysis of articles made of cast iron based on increasing the precision of the measurement of the velocity of acoustic vibrations through extraction of the ultrasonic bottom echo signal from the structural noise by means of space-time signal processing.
