ECTS number : 3
Solidification
The objective is to describe and present analytical models of different solidification microstructures (single crystal, dendritic, eutectic,...) in binary and ternary alloys, with emphasis on non-equilibrium problems and their impact on the final microstructure. On this basis, we will then analyse the experimental challenges and analyse the solidification microstructure and properties of single crystal turbine blades made of Ni-based superalloys.
Solid state transformations
The nature, mechanisms and kinetics of solid state phase transformations are described and modelled, with the aim of using these transformations to control the final microstructures of the material. Three classes of microstructure instabilities are studied according to the nature of the driving energy:
These concepts are illustrated by classical examples of metallurgy of carbon steels and structurally hardened aluminium alloys.
