A preliminary investigation of acousto-ultrasonic NDE of metal matrix composite test specimens

Technical Report ·
OSTI ID:5406092

Acousto-ultrasonic (AU) measurements were performed on a series of tensile specimens composed of 8 laminated layers of continuous, SiC fiber reinforced Ti{sup -15}- matrix. The following subject areas are covered: AU signal analysis; tensile behavior; AU and interrupted tensile tests; AU and thermally cycled specimens; AU and stiffness; and AU and specimen geometry.
