Introduction to materials science [ LMAPR1805 ]

> https://icampus.uclouvain.be/claroline/course/index.php?cid=MAPR1805

The objective of the course is to provide an introduction to materials science as a science that aims at linking the process, structure and properties of materials on the basis of the principles of chemistry, physico-chemistry, thermodynamics, quantum mechanics, physics and mechanics of solids.

Contribution of the course to the program objectives

Having regard to the LO of the programme 'Bachelor in engineering', this activitycontributes to the development and acquisition of the following LO:

LO 1.1 1.2

Specific learning outcomes of the course

At the end of this course, the student will be able to

• LO1.1. position materials science within its wider context of a discipline useful in most engineering technologies;
• LO1.1 know, define, and correctly use the vocabulary and notations of the discipline (e.g. capacity of define notions like lattice, atom, molecule, phase, eutectic, electron, phonon, tacticity, grain, precipitate, dislocation, conformation, stress, strain, stiffness, strength, conductivity, etc);
• LO1.1 describe with words and schematic drawings the chemical bonds at the basis of the different classes of materials, the amorphous and crystalline structures, the crystalline defects, the molecular architecture and microstructure, the physico-chemical/thermodynamics mechanisms at the origin of the microstructures;
• LO1.2 apply the basic concepts of crystallography, thermodynamics and phase diagrams to the solution of simple exercises;
• LO1.1 explain based on words and schematic drawings the links between the material structure and the functional (electrical and thermal conductivity, optical indices, dielectric and magnetic coefficients, etc) and mechanical properties (enthalpic and entropic elasticity, glass transition, strength, ductility, etc);
• LO1.1 master the notations, time, length and temperature scales, orders of magnitudes involved in the representation of the evolution of the functional and mechanical properties of the difference classes of materials;
• LO1.1 derive, based on the properties, the main field of applications of the classes of materials based on a global vision of materials science which goes beyond the classes of materials but which also explains the particular behaviours.

The students will be individually graded based on a written exam with questions related to the material seen during the ex-cathedra courses, as well as the solution of exercises in the vein of those addressed during the semester. 

Ex-cathedra courses and practical exercises mainly. One or two laboratories.
