Metallic Materials

Recommended Prerequisites

Structure and Properties of Matter.

Teaching Methods

The concepts of engineering metallic alloys are taught in teoretical lectures. Discussion about its importance for the future Mechanical Engineer is stimulated. TP classes reinforce these concepts by giving particular emphasis to structure-properties-application relationship. Classes will be always supported by examples of equipment manufacturing with major media impact. In all classes, proactive stances by the students is encouraged, necessary for skills acquisition.

Learning Outcomes

Knowledge of the different materials used in engineering is one of the main specific skills  required for a mechanical engineer. In order to be able to intervene in the production and processing of materials as in the conception and development of engineering projects, the mechanical engineer must have comprehensive knowledge not only about the nature of the different types of materials, but also a precise and quantitative knowledge of the properties of each material. The discipline of Metallic Materials aims to provide expertise on structure / properties / processing / performance alloys, ferrous and non ferrous, emphasizing the technological and economic aspects that should govern its application in engineering components.
