Learning outcomes of the course unit

Students will lern of the principles and application potentials of the basic methods for structural and phase analyses, inclusive of taking and preparing samples.

Prerequisites

The study of experimental methods employed in the analysis of the structure (morphology and phase composition) of materials requires the knowledge of physics and mathematics as provided in the course of BSc studies, and also the knowledge of materials sciences and materials engineering at least on the level of a graduate of the Bachelor´s degree of the mechanical engineering study.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Exam: written and oral parts. Awarding the course-unit credit is conditional on the elaboration of assigned sets of problems.

Course curriculum

Not applicable.

Work placements

Not applicable.

Aims

The course objective is to offer students an overview and, to a lesser extent, also the theoretical knowledge and principles of all basic methods for structural and phase analyses (physical principles of methods, instrument parameters, application scope of the methods, etc.), inclusive of sample preparation. Based on practical applications, students will have gained a basic overview of methodological procedures used in solving problems and analysing results.

Specification of controlled education, way of implementation and compensation for absences

Compulsory attendance at exercises. Absence from classes is dealt with individually, usually by make-up exercises.

Recommended optional programme components

Not applicable.
