Ultrasonic Characterization of High Manganese Austenitic Steel Parts for Longevity and Service Life

In this investigation the relationship between grain size of High Manganese Steel and ultrasound attenuation coefficient have been studied with a miniature UT pulser-received. It’s been found that there is good agreement between experimental data and exponential/logarithmic odel.Meanwhile such a system can be used for determining the degree of heat treatment and the resulting grain size variations
