    Abstract

    An ultrasonic technique using critically refracted longitudinal (LOR) waves was used to determine the residual stresses in ductile iron bars in the as-cast, annealed, normalized as well as quenched and tempered states. The results conform to expected trends based on differential cooling rate and phase transformation effects.
