Presentation
The course unit Materials Engineering introduces the fundamentals of materials science and engineering, covering atomic structure and bonding, crystalline and amorphous structures, solidification processes, and crystal defects. It includes the study of the mechanical properties of metals and related tests (tensile, hardness, toughness, fatigue, and creep), as well as phase diagrams, the iron-carbon diagram, and steel manufacturing processes. Additionally, polymers and composites are introduced, with their structural characteristics and applications. The scope lies at the interface between materials engineering and industrial production, being essential to understand the relationship between microstructure, properties, and performance. Its relevance in the study cycle stems from the need to strategically select and apply materials, ensuring innovation, efficiency, and sustainability.

Teaching methodologies
Teaching methodologies
The course adopts active methodologies that combine lectures, practical classes, and digital resources to enhance understanding and application of contents. Explanatory videos and simulations are used to visualize abstract concepts such as crystal structures, phase diagrams, and material defects. Students carry out practical assignments that promote research, critical thinking, and real application. Industrial case studies are also discussed, strengthening the link between theory and practice. Additionally, the Moodle platform is used for sharing materials, assignments, and submissions, while tutorials and support sessions assist autonomous learning.

Assessment
Assessment
A avaliação será feita de forma contínua da seguinte forma e com o seguinte peso na nota final :
- Assiduidade e participação nas aulas. 10% de peso na nota final
- 2 Testes ao longo do ano com 25% de peso cada . ( 2 x 25%)
- 4 Trabalhos de grupo com apresentação oral (considerado como elemento de avaliação com peso superior ao do trabalho escrito) com 10% de peso cada (4 x 10%)
Para realizar a aprovação por avaliação contínua é necessário obter um minimo de 8 valores nas provas de avaliação.
Terá aproveitamento o/a aluno/a que obtenha uma média final de 9,5 valores .
Em caso de dúvida do professor sobre o valor da nota obtida pelo aluno em qualquer dos testes ou trabalho será feita uma prova oral complementar sobre toda a matéria do teste ou exame.
A não entrega do trabalho ou não comparência a um teste implicará ter a nota de zero valores à prova que não compareceu ou não entregou o trabalho
