Learning Outcomes
Transmitting materials basic knowledge regarding the internal structure and the physical, chemical and mechanical major classes of materials available on the market and, in particular, for the specific case of metallic materials develop practical and theoretical powers to recognize the influence of chemical composition and processing method in the mechanical and technological characteristics tested. Finally, the most relevant mechanical tests, traction, hardness, impact and fatigue will be addressed, in order to determine the main mechanical properties of the materials.
After the frequency with approval of Materials Science, the student will be able to:
LB1 - to know, to identify and to characterize the different types of materials and to discuss its importance in the engineering development;
LB2 - to select and perform the most appropriate mechanical tests to determine the main mechanical properties of metallic materials;
LB3 - to interpret the mechanical, physical and chemical properties of metallic materials knowing their crystalline structure;
LB4 - to know the mechanisms of diffusion in the solid state and the laws that govern them and use this knowledge in the interpretation of surface treatments on metal and semiconductor doping;
LB5 - to explain and to apply the knowledge about crystalline structures and solidification in the interpretation and analyze of phase diagrams;
LB6 - to interpret and to analyze any binary phase diagram.
