Entry requirements

The participant is expected to have completed courses in Inorganic Chemistry NV1, 10 credit points or have equivalent knowledge. The courses Physics MN1, 10 credit points. Physical Chemistry MN1, 10 credit points and Chemical Bonding MN1, 10 credit points, are recommended.

Aims

After completing the course the student should be able to:

- classify defects from dimensionality, describe dislocations with emphasis on Burgers vector, elastic energy, how they move and if a dislocation reaction is possible.

- describe and state the conditions for Fick's diffusion laws and apply them to solve diffusion problems, describe some diffusion mechanisms, state some parameters affecting diffusion.

- define ideal and non-ideal solid solubility, explain excess free energy, analyse the interdependence between excess free energy and the shape of phase diagrams, predict the microstructure using phase diagrams.

- explain homogeneous and heterogeneous nucleation and state the effect of undercooling, describe solidification of melts, explain equilibrium and non-equilibrium solidification in binary systems, describe shear and reconstructive transformations in the solid state, classify precipitates using lattice coherence, predict the relationship between the geometrical shape of precipitates and the elastic energy, construct TTT diagrams from transformation rate measurements.

- outline the technologically important Fe-C phase diagram, predict the microstructure for different steels and cooling rates, predict the effect of different alloying elements on the austenitic transformation, describe and state the most important advantages/disadvantages with other technologically important alloys (Al, Mg, Be, Ti, Cu, refractory metals, Co, Ni, noble metals).

- describe some methods for materials synthesis

- describe some methods for materials synthesis.

- explain elastic and plastic deformation, define modulus of elasticity, yield strength, tensile strength and hardness, state some types of fracture, describe crack initiation, crack propagation, fatigue and creep, explain some hardening procedures.

- perform simple modelling of binary phase diagrams including calculations of phase equilibria.

Communication training is integrated in the materials science courses. In this course the student will especially train to:

- describe the technological use of a metallic alloying system.

- search articles in scientific journals and information on www.

- present the project both orally and in writing.

- be opponent on another presentation.

Laboratory work: Metallography. Mechanical properties. Synthesis of materials. Diffusion. Theoretical modelling of phase diagrams.

Instruction

Lectures, lessons, laboratory work, seminars.

Assessment

Written examination at the end of the course. Passed project presentation (orally and in writing) is also required as well as passed laboratory course which is assigned 2 points.
