25983 - Materials Science

DESCRIPTION & CONTEXTUALISATION OF THE SUBJECT

The subject called -Materials Science- is a compulsory subject and therefore essential, given the importance of knowing
to the fullest possible extent the materials that are used in engineering for all type of components and devices, and the
way these materials should be managed to achieve their best benefits. The contents of the course are undoubtedly basic
or fundamental, but also they affect the practical application of the knowledge acquired in multiple facets of engineering.
Fundamental knowledge of mathematics and chemistry are important.

COMPETENCIES/LEARNING RESULTS FOR THE SUBJECT

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.

METHODS

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.

ASSESSMENT SYSTEMS

- Continuous assessment system

- Final assessment system

 

TOOLS USED & GRADING PERCENTAGES

- Extended written exam 60%
- Practical work (exercises, case studies & problems set) 15%
- Individual work 10%

 

ORDINARY EXAM CALL: GUIDELINES & DECLINING TO SIT

The evaluation criteria in the ordinary call will be:
- Midterm exam: with problems and short questions of theory. 15% of the final grade.
- Practices: are mandatory and account for 15% of the final grade. The student will deliver a report for each practice
within the period prescribed by the lecturer and will take a written practices test at the end of the semester. The final
practices grade will be obtained from both: 40% of the reports and 60% of the written test.
- Individual tasks: involves the resolution of problems proposed by the lecturer and accounts for 10% of the final grade.
- Final exam: 60% of the final grade. Problems and theoretical questions.
In order to pass the course, students must pass the final exams and the practices exam. Otherwise, both will have to be
repeated. When a student takes the final exam or the practices exam, is participating in this call. To give up the call the
student does not have to take part in any of the two exams.
In case of resignation of the continuous assessment within the established deadlines, a final assessment of the subject
will be done by means of a final written exam (85%) and a practical exam (15%).

 

EXTRAORDINARY EXAM CALL: GUIDELINES & DECLINING TO SIT

In the extraordinary call the final evaluation system will be applied
