The lecture WK I deals with the basics of material physics. Chapters I and II cover the type of bond as well as the structure and composition of a crystalline solid. This is followed in Chapter III by a short introduction to the theory of elasticity, which includes a description and experimental determination of the moduli of elasticity. The chapter ends with the theoretical shear strength of ideal crystals.
Consequently, the 4th and 5th chapters deal with real, i.e. defective crystals. These include point-like (empty interstitial and foreign atoms) and linear (dislocations) as well as planar crystal defects (grain boundaries).
Chapter 6 deals with methods for structure and microstructure investigation, such as light microscopy or electron microscopy. In addition, alternative methods such as scanning tunnelling microscopy or classical methods such as hardness measurement provide information about the surfaces or mechanical condition of metallic and non-metallic materials.
In chapter 8 of the lecture the atomic transport (diffusion) in crystalline solids is presented. Besides a phenomenological description of diffusion, simple solutions of the diffusion equation are derived and used to estimate the effectiveness of atomic transport.
