Nondestructive Testing of Diffusion Bonded Titanium Alloys for Engine and Airframe Components

Abstract

The development and evaluation of ultrasonic instrumentation for the nondestructive testing of diffusion bonded titanium alloy components is described. Results of a survey to define potential diffusion bonding deficiencies are given. A signal-averaging pulse-echo system developed to increase defect signal-to-grain noise ratio is described. The AFML Computer-Automated Ultrasonic Inspection System was used to evaluate displaced and angularized bond planes. Diffusion bonded internal defect specimens were evaluated by blue-etch-anodize, fluorescent penetrant, signal-averaged pulse-echo, and Delta-Scan techniques. Ultrasonic attenuation measurements versus grain size are reported. Static tensile and axial fatigue data are reported and correlated with nondestructive evaluation and fractographic results. Acoustic emission behavior of parent material specimens is compared with that of internal defect specimens.
