The evaluation of two nondestructive testing (NDT) techniques for the flaw inspection of turbine disk material for the General Electric T-700 engine is described. The material, which is produced by the hot iso-static pressing (HIP) technique, introduces a new set of NDT requirements and problems. The first technique evaluated is neutron radiographic inspection. It proves to be capable of detecting flaws; however, a certain degree of development work is required to improve its resolution capability. A newly developed photon scattering gauge was evaluated as the second technique. Although tailored for the inspection of explosive filler in 105-mm projectiles, the existing test instrument demonstrates the feasibility of the technique for the inspection of HIP turbine parts. The response of the photon scattering gauge is three dimensional. It is characterized by its high-resolution capability.
