Students are expected to have completed:
Aerospace Materials I
Competences and skills that will be acquired and learning results:
To understand the structure, composition, processing, properties and performance of different families of metallic materials used in aerospace and relationship among them.
To be able to select metallic materials for applications in different aerospace engineering fields.
To know the more adequate standardized tests to evaluate properties and performance of metallic materials, and to analyze the results.
Regarding general capabilities or skills, during the year, students will acquire the following abilities:
- Ability to solve complex problems.
- Ability to look for, to understand and to differentiate the relevant information to be able to take a decision.
- Ability to use multi-disciplinary knowledge to solve a problem.
- Ability to work in groups and distribute work to face up to complex problems.

Learning activities and methodology:
-The course will consist of Master Classes where the theory of the topics will be presented and Tutorial Classes where applications and examples will be emphasized and problems exercises will be solved
- There will be tutorial sessions for the students
- There will be 6 hours of practical laboratory work of compulsory assistance. The laboratory sessions will result in the acquisition of practical abilities related to the content of the course
- All the teaching material (lecture notes, handouts, exercises and problems, laboratory manual and additional material) will be distributed to the students through aula global
Continuous evaluation will consist of two parts:
(i)exercises and tests to be solved in groups or individually, during classes, or other activities (at least 3 activities) that will count 30% of the total mark.
(ii)laboratory practices, that will be assessed with a questionnaire that will be handed in at the end of each laboratory session, and that will count 10% of the total mark.
Percentage of continuous evaluation assessment (exercises, tests, laboratory): 40
-The final examination is will count for 60% of the total mark of the lecture course. Help sessions and tutorial classes will be held prior to the final exam.
Percentage of end-of-term-examination: 60
Minimum mark for end-of-term-examination: 5
In order to pass, the final mark must be at least 5.
