  • Correlation between corrosion rate and ultrasonic attenuation on steel 
    Dayananda, HGSM [Thesis-Abstract]
    Corrosion is the gradual destruction of material, usually metal, by chemical reaction with its environment. Usually the corrosion rate cannot be measured directly which needs sample preparation, fixing of samples in a ...
  • Correlation between ultrasonic attenuation and hardness of tool steels 
    Dayananda, HGSM; Munasinghe, RGNDS; Sivahar, V [Conference-Abstract]
    Theory of propagation and reflection of ultrasonic waves in metals in used to locate the internal defects of engineering components. It is observed that the energy absorption of ultrasonic waves (attenuation) in a metal ...
