Objectives

Justification
The knowledge of metallographic techniques and their application to the study and characterization of the various engineering materials, is vital to all material engineers and, therefore, essential in the curriculum of the MIEMM. Thus, this course unit is expected to provide students competences in the preparation and analysis of materials samples, essential for developing experimental work in other course units or investigation projects. Given future professional situations in which students could be involved, as manufacturing process control and product conformity inspection, this course unit will also capacitate students to act autonomously and in accordance to the relevant test norms.

Goals
- Application of sampling and preparation techniques in accordance to the applicable norms;
- Microscopic analysis and image processing;
- Quantitative microstructural analysis methodologies.

Skills and Learning Outcomes
Students are expected to:
- master sampling and preparation techniques, microscopic analysis and image processing;
- apply quantitative microstructural analysis methods and get acquainted with automatic image analysis systems;
- develop team work and communication skills (oral and written);

Program

Introduction to materialography.
Sampling.
Methods, equipment, materials and techniques of sample preparation: sectioning, mounting and polishing.
Methods of microstructural contrast.
Optical Microscopy
Quantitative metallography.
Automatic image analysis systems.

Evaluation Type

Distributed evaluation without final exam

Eligibility for exams

To be admitted to exams, students:
- have to do all the practical assignments and the corresponding reports and presentations.
- cannot miss more than 25 % of the practical classes.
- have to reach a minimum grade of 10 out of 20 in the practical component.

Calculation formula of final grade

Final Grade = 60% of the practical grade (average grade of the written reports and oral presentations) + 40% of the average grade of the mini-tests.

Examinations or Special Assignments

See Special Assessment

Special assessment (TE, DA, ...)

A written exam (40% of the final grade) plus a practical assignment which comprises a written report and an oral presentation (60% of the final grade).
To complete this course unit, students have to reach a minimum grade of 10 out of 20.

Classification improvement

Students can improve the theoretical-practical component by attending an extra exam.

Observations

Recommended prerequisites: concepts learnt on the course units of Introduction to Materials Engineering I and Equilibrium Diagrams.
