Paper No: IPC2000-206
.... In-line inspection tools both must detect mechanical damage and characterize parameters such as microstructure changes, residual stresses and extent of removed metal. These are the parameters that determine whether a defect is a candidate for delayed failure. Magnetic flux leakage (MFL) is commonly used...
