Book Description
The report covers exploratory development of nondestructive testing techniques for solid-state diffusion-bonded parts. A literature survey describes the current inspection practices employed on diffusion-bonded laminates and the nature of the interface and bond properties. Test specimens of titanium, columbium, and TD-nickel were prepared for evaluating various test methods. The specimens provided a range of thicknesses and varying degree of bond quality as determined by mechanical property tests. In addition, a number of diffusion-bonded specimens were supplied by the Air Force. Conventional ultrasonic techniques and recently developed selective interface inspection techniques clearly indicate bond conditions where these vary from a no-bond condition to substandard bonds. A number of methods show potential correlation between a quantitative expression of bond quality such as shear or tensile strength. These methods include longitudinal and shear wave velocity, ultrasonic attenuation, and vibration analysis. (Author).
