Abstract

A study has been made on the correlation between ultrasonic attenuation and mechanical properties with different prior austenite grain size. It was found that ultrasonic attenuation is increased with increasing grain size, decreasing yield strength and increasing charpy impact energy value for ALSI 4140 steel.
