Ductile cast iron round bars was prepared using alloys with carbon equivalent percentage (C.E) in the range (4.50% and 4.76%). Ultrasonic velocity and attenuation measured using pulse echo technique of frequencies 1, 2 and 4MHz .It found that ultrasonic velocity decreases with increasing size of casting module, while attenuation coefficient increases. In addition, the nodule count decreases with increasing the size of casting module, at the same time nodule size increases. An empirical formula relating the ultrasonic velocity and the mechanical properties namely ultimate strength, 0.2%-offset yield, elongation and hardness) is suggested.
