Ultrasonics and X-ray radiographic nondestructive inspection techniques have been evaluated and compared with the ultimate goal of developing quality assurance procedures for use in the manufacture of basic structural shapes of Graphite/Aluminum Metal Matrix Composites. To achieve this end, Gr/Aℓ wire, basic panel, structural shapes and stringer stiffened panels were nondestructively inspected, tested, and the defects microstructurally characterized. Flaw indications observed in X-ray radiographic and ultrasonic inspections were interpreted by metallographic examination. The Defect-Property Sensitivity Analysis (DPSA) program is a continuing effort directed at a more rigorous definition of test variables. (Refs. 1 through 4).
