In this chapter, various electromagnetic NDE techniques such as eddy current, magnetic, micro-magnetic, potential drop and microwave techniques for materials characterization are covered. For each technique, principle, instrumentation along with sensors, capabilities, applications, and recent advances towards quantitative characterization of defects, microstructures and residual stresses in engineering materials are given. Special emphasis is also given to numerical modelling, sensors and signal processing for automated NDE.
Engineering components and structures in power, chemical, petrochemical, fertiliser, transport and other industry are usually subjected to complex service environment viz. exposure to elevated temperature, hostile media, loading, transients etc. causing formation...
