Abstract:Ultrasonic testing has a strong application in defect detection. An efficient tool for characterizing and life assessment of material structure and components by nondestructive ultrasonic velocity was developed about thirty years ago. Cold rolling results in increase in strength and hardness. The work discussed here is to study quantitative ultrasonic longitudinal velocity for characterizing a change in microstructure due to cold rolling in austenitic stainless steel samples. Samples were cold rolled upto 80 p… Show more
