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
