A review provided about non-destructive testing (NDT) method that is ultrasonic technique for the characterization of casting material. The review considers the capabilities of Ultrasonic Testing (UT) with respect to advantages and disadvantages of this method. Then, method categorized based on their intrinsic characteristics and their applications. The aim of this study is the investigation of the capability of ultrasonic technique in assessment of the structure and properties of nodular cast iron and to provide additional data concerning the particulars of the use ultrasonic velocity and attenuation measurements for quality control of different grades of ductile iron either in the as-cast condition or after heat treatment. In the measurements, first the directional dependence of velocity and apparent attenuation can be investigated. Ultrasonic velocity and apparent attenuation measurements can be carried out at various testing frequencies to observe the effect of the probe frequency. The nodularity status can be examined by metallographic investigations and hardness tests were performed. Finally, the results of ultrasonic velocity measurements, metallographic investigations and mechanical tests can be compared. Thus; Ultrasonic Technique is effective quality control tool which can be used for characterization of casting materials.
