Course detail
Experimental Methods in Materials Engineering
FSI-WEM Acad. year: 2016/2017 Winter semester
Basic methods for the preparation, observation and evaluation of the structure of metallic and non-metallic (ceramics, composites, plastics, concretes, wood) materials, using modern analytical methods (light and electron microscopies, X-ray analysis, spectroscopy, etc.). Assessment of the relations between the structure and the mechanical and physical properties of materials. The students will further be made familiar with the evaluation of the structure of a material on the basis of current standards, and they will apply their knowledge to practical problems.

Learning outcomes of the course unit
The knowledge of the principles and application potentials of the basic methods of structure and phase analysis, inclusive of procedures of taking and preparing specimens. Separate evaluation of structure components for all the kinds of materials under study, and assessment of the relations between the production technology, structure, and useful properties of materials.
Prerequisites
The study of the experimental methods used in the structure analysis (morphology and phase composition) of materials requires the basic knowledge of physics and mathematics on the level offered in the course of bachelor studies, and also knowledge of materials science and engineering – on the level of BSc at the least.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Exam: written and oral parts. Awarding the course-unit credit is conditional on the elaboration of protocols, full attendance and credit test.
Aims
The goal of the course is to give students a survey and, to a lesser extent, the theoretical knowledge and principles of all the basic methods for the structure and phase analysis (physical principles of the methods, instrument parameters, application scope of the methods, etc.), inclusive of specimen preparation.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is compulsory. Absence from seminars may be compensated for by the agreement with the teacher.
