A numerical integration ultrasonic field analysis computation model is outlined and a variety of experimental and analytical techniques are illustrated for characterizing the anisotropic nature and the corresponding grain structure associated with centrifugally cast stainless steel. The feasibility of using simple techniques such as skip distance, critical angle, and surface wave velocity measurements to obtain preliminary material properties is demonstrated. The question of choosing the proper propagation mode from which the direction of the anisotropic vector can be established is addressed. Ultrasonic field and phase velocity profiles are given and skew angles are graphed and compared to experimental and classical techniques.
