Abstract:
In recent years the expectations of non-destructive testing and evaluation (NDT&E) service users have increased from simple defect detection and dimension estimation to the provision of quantitative information about material properties including microstructure, stresses, hardness, etc. Although there are many techniques available to NDT&E service providers, each have their own limitations when used in isolation. For example, magnetic Barkhausen emission measurement has good microstructure and stress characterisation capabilities, but has a limited measurement depth. which is problematic where the property of interest varies with depth, i.e. case hardening. Magnetic flux leakage can detect defects on both the surface under inspection and the opposite surface, but it is very difficult to discriminate between them. However, if two or more inspection techniques are combined in a single system, it is thought that it may be possible to overcome these limitations.
