Structure and Properties of Advanced Materials
FSI-TVN Acad. year: 2020/2021 Summer semester
Crystalline structure, microstructure, mechanical properties. Prediction of materials characteristics. Application of selected advanced materials in the engineering practice. Nanostructured materials – carbon fibers, nanolayers and nanotubes, bulk magnetic nanomaterials and ultra-fine grained materials. Shape-memory alloys – shape-memory effect and principles of mechatronic actuators. Composite materials – fiber- and particle-reinforced composites and laminates.

Learning outcomes of the course unit
The student gains basic information concerning structure, mechanical properties, and applications of advanced materials in recent engineering and technology.
Prerequisites
Solid State Physics, Materials Science and Engineering.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
The assessment of a student is made upon his performance in practice and results of a final test.
Aims
The main aim lies in elucidation of unique microstructure of advanced materials as well as in understanding a physical nature of relationship between the microstructure and mechanical properties of such materials. The student also gains basic information about possibilities of application of these materials in the recent engineering practice.
Specification of controlled education, way of implementation and compensation for absences
The presence of students at practice is obligatory and is monitored by a tutor. The way how to compensate missed practice lessons will be decided by a tutor depending on the range and content of the missed lessons.
