PREREQUISITES
Basic knowledge of materials science

COURSE AIM
The course will deal with the important principles of phase transformation. Attention will focus on the basic theory of the interaction of defects (vacancies, dislocations, interphase interfaces etc), general laws of phase transformation and mutual effects between composition, microstructure and macroproperties of engineering materials such as metallic alloys and ceramics. The knowledge of composition design, microstructure development and property improvement will be emphasized. The newest development of materials and methods of doing research in materials science will be discussed.

CONTENTS
Theoretical background
1. Thermodynamics and kinetics of alloys: binary and ternary systems; kinetics of transformation.
2. Diffusion: interstitial and substitutional diffusion, the relationship between macroscopic diffusion and atomic mechanisms; mass transfer in porous materials and other transport phenomena.
3. Interfaces and surfaces: structures and properties of surfaces, grain boundaries and interphase interfaces; the effect of interfaces on transformation.
4. Solidification and melting: casting; welding technology; continuous casting.
5. Diffusional transformation: general theory of nucleation and growth; important phase transformations such as precipitate, massive, spinodal, ordering transformation etc; transformation of steels.
6. Diffusionless transformations: the crystallography and kinetics of nucleation and growth of Martensite transformation; shape memory materials.
