Objectives:

- Study of the structure-properties relationships of engineering materials.

- Description of the main mechanical tests carried out to materials.

- Study of the characteristics of metals, ceramics, polymers and composites. Selection criteria.



Learning outcomes:

- Employ appropriately the specific terminology of the subject, expressing the basic fundamentals of materials science by the proper use of graphic, mathematical and verbal language.

- Distinguish the main types of materials and relate their different characteristics with their various applications.

- Link the internal structure of materials with their specific physicochemical and mechanical properties, establishing the impact these properties have on the practical use of each material.

- Understand the concept of equilibrium state of a material and reason in which way a mechanical or thermal treatment may change the equilibrium state and, therefore, the material properties.

- Work cooperatively in tasks framed in the field of materials science, dealing with team tasks and analyzing and discussing ideas contributed by the other team members.

Practical contents:

The following practices will be carried out:



Practice 1: Introduction to materials

Practice 2: Hardness of materials

Practice 3: Tensile test of materials

Practice 4: Crystallography. Study of crystallographic directions and planes.

Practice 5: Thermal treatments in metals.

Practice 6: Microstructures observation.

Practice 7: Experimental observation of corrosion.

During the classroom hours master classes will be given, problems classes will be carried out and finally laboratory practices will be performed. In the master classes PowerPoint presentations will be carried out by the lecturer, during the problems classes problems will be proposed by the lecturer and time will be dedicated to their resolution, sometimes they will be resolved in group. In the laboratory activities the students will be distributed in small groups and they will perform practical work with laboratory equipment, whenever possible.

In the event that the sanitary conditions prevent the face-to-face teaching activity and / or evaluation, a non-face-to-face modality will be activated and the students will be informed promptly.

The evaluation criteria in the ordinary call will be the following:



- In order to pass the subject, the student must pass, with a score of 5 points out of 10, a minimum content theory test (Item 1). Students will have three opportunities to pass this test. The first test will take place during the first week of October. The remaining two opportunities will be on the days set for the official examination of the ordinary and extraordinary calls for the subject. In case of not passing the test, the student will not be able to pass the subject.



- Official ordinary call exam: The exam will account for 80% of the final grade and will consist of two different parts, a theoretical part and problems. The theory part will account for 40% of the grade and that of problems 60%. In order to pass the subject, the student must achieve at least a score of 4 points out of 10 in each of the parts.



- Laboratory practices: Carrying out the practices is mandatory and represents 20% of the final grade. Prior to practice, the student must review the corresponding script as well as the related concepts presented in the classroom. If the teacher detects that said previous work has not been carried out, it could prevent the development of the practice in the laboratory. All practices will be evaluated. To do this, the student will deliver the corresponding evaluation report or test for each practice. At the end of the practices, a written practice exam will be included at the end of the semester. The final grade for practices will be obtained from both tests, 40% reports/test and 60% written test.



- In order to pass the subject and do the corresponding averages, the exams and practices must be passed. If not, they will have to be repeated.



- When a student takes the exam or the practice exam, he or she is participating in said call. To waive the call, you must not take either of the two exams.



- In the event that health conditions prevent the performance of a teaching activity and/or face-to-face evaluation, a non-face-to-face modality will be activated, of which the students will be promptly informed.
