GATE Metallurgy : Xray diffraxtion covered

  X-Ray Diffraction ·          Electrons from a filament directed toward target material by applying a high electric field. This electron then strikes on target materials which result in heat X-ray radiation. ·          These X-rays then directed toward sample need to be analyze ·          X-ray diffraction used to determine crystal structure, phase identification, crystal size, crystallographic texture, defect studies, thin-film quality and residual stresses.   ·            The wavelength of X-rays for diffraction falls in the range of 0.5-2 A 0   ·          Bragg’s law: Essential condition for diffraction results in constructive interference to occur                     ...
