Non-Destructive Testing Methods

Residual stresses can be measured non-destructively with X-ray diffraction method. X-ray diffraction provides reliable and objective data for quality control assessment. X-rays have high energy and short wavelength when compared to visible light making them ideal for probing the interplanar distances in crystalline materials.

Barkhausen noise analysis is a non-destructive method involving the measurement of a noise like signal induced in a ferromagnetic material by an applied magnetic field.
