Course detail
Theory of Phase Transformations
FSI-9WTF Acad. year: 2023/2024 Both semester
The subject carries on and crowns similar items included in the magister degree of study. In a thorough way and using detail analyses it applies principles of chemical thermodynamics and diffusion, theories of reaction rates and phase interface, as well as statistical theories of transitions when dealing with complicated and less common phase transformations, e.g.spinodal decomposition, atomic ordering, high pressure phase transformations.The links between final structure and properties of the materials are not omitted.

Entry knowledge
Basic knowledge of the principles of chemical thermodynamics, theory of reaction rates and diffussion applied to main phase transformations occuring in the iron – carbon systemes and alloys.
Rules for evaluation and completion of the course
Periodic tutorials – continuous monitoring of the learning process and progress. Solving given problems. Approving application skills. Final assessment by means of professional discourse.
Regular individual consultations possible after previos agreement with lecturer.
Aims
This subject aims to accomplish the treatment and undestanding of phase transformations occuring in certain types of materials (metals, ceramics, polymers, composites). In many cases these materials have been developed independently. Anyhow, similarities found among the principles underlying various disciplines and procedures have led to the discovery of common phenomena and mechanisms. To offer deep knowledge of them together with application-oriented skills are the main goals of this subject.
Subject outcomes: broadened and deepened understanding and knowleddge of the principles of chemical thermodynamics, kinetics and diffusion applied to phase transformations occuring in various types of materials. New findings about less current types of phase transformtions. Application-oriented skills enabling the design and use of phase transformations when striving for desired structure and properties of materials.
