Class Materials Engineering

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.

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.
