Aim: To provide knowledge of the most important materials of construction among metals, cerams, polymers, and composites.
To give an understanding of mechanical and chemical properties of materials of construction in dependence of structure (atomic, micro, and macro), chemical composition and treatment during fabrication. To provide knowledge of some commonly used methods of testing. To form a basis for selection of materials. To give an orientation about principles for development of materials with specific properties
