Overview of NDE development

Nondestructive examination technology is an important part of the CTAHE program. Development and application of advanced NDT are being performed by several ceramics producers, engine fabricators, research and development organizations and NDT companies. Advanced and improved techniques are being studied for examination of ceramics at all stages of fabrication from the starting raw materials through intermediate stages, to the final finished product. The very small size of critical flaws [e.g., 50--100 {mu}m (0.002--0.004 in)] in the finished product adds to the challenge of development. This paper will provide an overview of some of the studies and results.
