Boron carbide is widely used to provide ballistic protection in many challenging service environments. This work was undertaken to determine a suitable process for NDT characterization of Boron Carbide. The project involves the introduction of deliberate flaws within the Boron Carbide during processing. An extensive experimental programme of work has been undertaken to establish the best NDT technique for the defect detection and material characterization of Boron Carbide tiles. A number of different techniques such as ultrasonic immersion testing, digital X-ray testing and microwave testing have been employed to establish the capabilities and limitations of each of the techniques. Ultrasonic immersion characterization of the material was found to be able to detect both subtle material density variation and flaws within the material. The detection capabilities and resolution of the technique was found to be dependent upon the focus depth of the ultrasonic beam. The data obtained from the ultrasonic characterization will be correlated with ballistic performance.
