Competences and skills that will be acquired and learning results. Further information on this link
Competences: In general, the student must develop skills and master the knowledge associated to the manufacture of components for specific applications. Specifically, the student must acquire the knowledge and skills associated to materials technology. This implies: 1) to acquire the knowledge of the fundamentals of science, technology and chemistry of materials and 2) to understand the relationship among microstructure, synthesis and/or processing and the properties of the materials. Furthermore, during the course, other skills will be promoted: - Ability to analyze and solve complex problems, encouraging skills for searching, understanding and identifying the most relevant information and analyzing and interpreting results obtained to reach a final decision. - Ability to correlate multidisciplinary knowledge to solve technological problems. Learning results: Acquisition of knowledge and skills to apply materials engineering in the achievement of components for specific applications. In more detail: - Ability to select the proper material for a specific application. - Ability to select a forming process for a particular material, considering size, shape, properties and final application. - Knowledge of the different joining processes, excluding mechanical fastening methods, understanding the chemical and/or metallurgical processes involved. - Knowledge of failure possibilities linked to in-service behavior, providing the capability to determine the cause of failure. - Knowledge of inspection and testing methods.

Learning activities and methodology
Master classes, reduced-group classes, individual tutorship and personal work of the student; focused on acquiring theoretical knowledge. Laboratory sessions, classes focused on solving problems, individual tutorships and personal work of the student; oriented to the acquisition of practical skills related to the program of the subject. Note: For the 2020/2021 academic year, teaching will be bimodal 50% (synchronous online teaching in big or aggregate groups, face-to-face teaching in small groups).
