2. Light microscopy. Scheme of the light microscope. Focal length. Depth of focus. Defects of thin lenses. Spatial resolution. Preparation of specimens for light microscopy. Revealing of microstructure of metals by chemical and electrolytic etching.
3. Basics of image analysis. Methods of image contrast enhancement. Microhardness testing. Confocal microscopy – principle, spatial resolution. Typical applications of light microscopy in materials engineering.
4. Interaction of electrons and X-rays photons with specimens. Diffraction on crystal lattice – Laue conditions, Bragg´s equation. Reciprocal lattice. Ewald´s sphere. Methods of X-ray diffraction analysis (XRD). Qualitative and quantitative XRD phase analyses of materials. Texture analysis. Evaluation of macro- and microstresses in engineering materials. Typical applications of X-ray analysis in materials engineering.
5. Transmission electron microscopy – basic principles. Contrast mechanisms in amorphous and crystalline materials. Amplitude contrast – bright field and dark field images. Phase contrast – lattice and structure imaging.
