General information

Subject type: Mandatory

Coordinator: Joan Triadó Aymerich

Trimester: Second term

Credits: 4

Teaching staff: 

Joan David Gutierrez Castillo

Teaching languages

  • Catalan
  • Spanish

The language of instruction will be Catalan/Castilian. Some materials, terminology and bibliography are in English, so it is advisable to have a minimum level.

Skills

Basic skills

  • B5_That students have developed those learning skills necessary to undertake further studies with a high degree of autonomy

     

Specific skills

  • Apply the fundamentals of the elasticity and strength of materials to the behavior of real solids

  • Have knowledge and skills for the application of materials engineering

Transversal competences

  • T2_That students have the ability to work as members of an interdisciplinary team either as one more member, or performing management tasks, in order to contribute to developing projects with pragmatism and a sense of responsibility, making commitments taking into account available resources

     

Description

The objective of the subject is for the student to acquire a broad view of the materials used and to know the main manufacturing processes that allow the production of components, for each family of materials. Study and learn the importance and relationship between microstructure and material properties, as well as the service performance of the different components.

 

 

Contents

The content of the subject is divided into 3 blocks:

I. Structure of Materials. Basic concepts of materials science.

II. Conventional materials in engineering: a) metals b) ceramics c) polymers

III. Advanced materials: composites

 

In Block I you will study:
1. Atomic structure and arrangement. Types of links. Classification of materials.
2. Movement of atoms: Diffusion and heat treatments in metals.
3. Solubility in solids.
4. Alloys. Phase diagrams.
5. Hardening of materials: hardening by solid solution, by precipitation, by martensitic transformation, by cold work.

In Block II you will study:
a) Metals: basic properties. Pure metals and alloys. Designation of the most important alloys. Ferrous alloys. Simple steels and alloy steels. Hardening. Cooling curves. Microstructures and their dependence on the cooling rate. Heat treatments. Non-ferrous alloys: aluminum and its alloys, titanium and its alloys, copper and its alloys, zinc and magnesium alloys. Superalloys. Use of metallic materials in industrial applications.

b) Ceramic materials: basic properties (atomic bond, ordering, imperfections in ceramic materials). Crystalline and non-crystalline ceramic materials. Phase diagrams of ceramics. Ceramics processing. Most important industrial ceramics: silicates, glass. Applications of ceramics.

c) Polymers. Structure of polymers. Formation of polymeric chains. Degree of polymerization. Types of polymers: thermoplastics, thermosets, elastomers. Thermal behavior. Amorphous and semi-crystalline polymers. Polymers for industrial use. Manufacture of industrial polymers. Vulcanization.

In Block III you study:
Composite materials (composites). Types of compounds and their manufacturing processes. Particle-reinforced composite materials, dispersion-hardened compounds, fiber-reinforced compounds. Laminar composite materials, sandwich or "sandwich" type materials. Wood. Concrete (concrete).

 

 

Evaluation system

The subject is passed by doing internships, assignments and written exams.

The practices will have a total weight of 30% in the final grade. The practices involve problems to be solved, laboratory tests and an individual work on a current topic related to Materials Engineering. Attendance of laboratory experiments is mandatory (otherwise the LAB report will not be evaluated). The article will count as one more laboratory practice.

The written exam grade will consist of a continuous assessment and a final exam. The continuous assessment will include the theoretical topics and will have a weight of 20% in the final grade. The final exam will be held at the end of the course. This exam will include practical problems and some theoretical concepts. The exam mark will have a weight of 30% in the final mark. The examination of books or notes will not be allowed in the exams.

The course work is done in groups, will have a weight of 20% and will have to be presented in class.

A minimum grade of 30 out of 100 is required in all concepts in order to be assessed.

Unexcused absence in more than 3 classes will mean the loss of the right to assessment.

 

RECOVERY:

Only the final exam can be retaken. Where the maximum score will be 5 (50/100).
