Structure and Properties of Materials
FSI-3SV-A Acad. year: 2024/2025 Winter semester
Phase transformations during the heat treatment of metals and alloys. Fundamental knowledge of structural materials (ferrous alloys and non-ferrous metals, ceramics, polymers, and composites) – their chemical composition and technological treatment in relation to their crystallographic, sub-structural, structural, and mechanical properties; degradation processes resulting from the application of these materials. Principles of selecting materials for engineering constructions.

3. Structure of real crystals (crystal lattice defects and their properties)
4. Thermodynamics of solids
5. Diffusion, diffusion processes
6. Phases in metallic and ceramic systems. Equilibrium diagrams

Rules for evaluation and completion of the course
Examination. The examination consists of written and oral part. In the written part, students answer four questions related to topics dealt with in the course of the semester. In the oral part, students answer questions resulting from the written part as well as examiner's additional questions.
Awarding the course. Participation in practices is mandatory, must be properly excused absence. Unit credit is conditional on having participated in all exercises and worked out the reports from exercises in keeping with the teacher's instructions. Absence from exercises must be accounted for. Students who have missed an exercise will be given an extra assignment. They will prove in the form of a written report that they have mastered the given topic.
Aims
The objective is to provide knowledge on the composition, structure, and treatment of materials in relation to their properties that are relevant for treatment technologies and design applications. It enables understanding the essence of the above processes and their mutual causal relations.
Technologists will be provided with the knowledge of the relations between the structure, sub-structure, and treatment properties of structural materials. Designers will learn about how to make full use of structural materials. For all materials (of both current and enhanced properties) the principles are defined for their technically and economically suitable application.
