Physics of materials

PHYS-307

Lecturer(s) :

Mari Daniele

Language:

English

Summary

This course illustrates some selected chapters of materials physics needed to understand the mechanical and structural properties of solids. This course deals in particular with the physics of dislocation. The diffusion and phase transformations are complementary bases.

Content

1. Materials, definitions, structure

Binding energy in metals, ceramics and polymers. Crystal structure and amorphous materials. Theory of elasticity: stress and strain fields.

2. Diffusion

Diffusion in alloys. Physical and chemical diffusion.

3. Plastic deformation and dislocations

Phenomenology. Deformation of single crystals. Burgers' vector. Elasticity theory: interactions among dislocations. Creation and annihilation of dislocations.

4. Dislocation dynamics

Friction forces due to the lattice, to point defects and to dislocations. Movement equations. Partial dislocations and stacking faults. Dissociation mechanisms: dislocations in face centred cubic metals.

5. Dislocation kinetics

Thermal activation of plastic deformation. Dislocation climb. Deformation tests. Relaxation phenomena and mechanical spectroscopy.

6. Thermodynamics of phase transformations

Thermodynamical principles of phase transformations.Phase diagrams. Alloy solidification. Solid-solid phase transformations.

Keywords

dislocations, deformation, diffusion, elasticity, phase transformations, melting, precipitation crystallography
