The curricular unit has as learning objective to make the students acquire knowledge about the different materials used in engineering that allow them to acquire skills to perceive the properties of the materials and to relate with their applications in engineering. Finally, students should acquire and develop skills in selecting materials for relevant industrial and technological applications in order to eliminate or reduce phenomena of degradation of equipment such as corrosion, mechanical fatigue, wear and friction.

1. Introduction to materials science and engineering: What is materials science and engineering. Material Classes. Issues related with the production, application, competition and trends in the use of materials.
2. Chemical bond, structure and properties of materials: Chemical bonds in materials. Crystalline structures: Polymorphism. Solidification, crystalline defects and solid diffusion. Solid solutions and phase equilibrium. Mechanical, electrical, magnetic and optical properties of materials.
3. Classification of materials as applied to Engineering: METALLIC MATERIALS: Classification, processing, thermal treatments. Designation and classification of different types of steel and non-ferrous alloys. Noble and refractory metals. POLYMERIC MATERIALS: Polymerisation reactions. Thermoplastic processing. Elastomers. Plastic deformation and reinforcement. CERAMIC MATERIALS: Synthesis and processing. COMPOSITE MATERIALS: Types of matrices (metallic, ceramic and polymeric), types of reinforcements Structures (sandwich, laminar, fibrous and particle). NANOMATERIALS: Nanoparticles, nanofibres, nanotubes, nanocomposites. Structure and properties of carbon nanotubes.
4. Selection of Materials for Engineering Applications: Selection methods. Criteria.
5. Material Degradation: Chemical and electrochemical corrosion of materials. Types of corrosion. Corrosion control. Mechanical wear. Types of wear. Lubrication and prevention. Material fatigue. Mechanism. S-N curves. Prevention.
