NDE (nondestructive evaluation) of structural ceramics using neutron radiography
The use of ceramic materials as structural components is a rapidly advancing technology at present. Ceramics can withstand the stresses of environments beyond those commonly endured by metallic materials. It is generally believed that past difficulties with the application of ceramics may be obviated with careful selection of starting materials and constant attention to processing variables. The authors have been exploring the use of neutron radiography as an NDE tool for the examination of green and fired ceramic bodies to assess the flaw population, particularly in the early stages of processing. Here, they illustrate the use of neutron radiography for the detection of spherical voids, cracks, and binder dispersion in ceramic bodies and illustrate how simple densitometric equipment is able to map out very useful mass density variations in ceramics, even those which cannot be discerned by a visual inspection of film images.
