3. Metallurgical and dimensional controls

3.1 Metallurgical NDT equipment

The application of investment casting to the aerospace industry, among others, was only made possible by the implementation of proven non-destructive testing (NDT) and quality assurance procedures.

The very precise dimensional and metallurgical characteristics imposed on jet engine parts (reduced dimensional tolerances on complex aerodynamic shapes obtained directly from the foundry, absence of cracks, micro-shrinkage, etc.), as well as better control of the foundry process, require the implementation of investigation methods that can assess, without altering the parts themselves, their metallurgical health and geometric conformity.), as well as better control of the foundry process, require the implementation of investigation...
