MAMAS MSc PROGR IN ADVANCED MATERIALS, Year 1 (compulsory)

Examiner:

Professor  Birger Karlsson



Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

Course is available to students admitted to IMP ADVANCED MATERIALS, PhD students in Materials Science and Engineering, and students following the M-programme at Chalmers.

Other students: individually.

Aim

The subject provides the student with theoretical background to phase transformations and the constitution of microstructures. These prinicples serve as a tools for understanding the effect of various treatments on structure and properties of materials.

Content

The course is comprised of following parts:
Thermodynamics and phase diagrams: Free energy, volume and surface energy, equilibrium conditions, modelling of solid and liquid systems, kinetics of phase transformations.
Diffusion: Atomistic and macroscopic modelling, activation, interstitial and substitution diffusion, diffusion in binary and ternary alloys.
Interfaces and microstructures: Free energy of interfaces, coherent and incoherent interfaces, precipitation interface migration, grain growth.
Solidification: Nucleation, growth, single and many component alloys, eutectic and peritectic solidification, ingot structures.
Diffusional transformation: Homogeneous and inhomogeneous nucleation in solids and liquids, grain growth, particle growth, transformation kinetics, different kinds of transformations.
Diffusionless transformation: Nucleation and growth of martensite.
Thermodynamic modelling: Principles and application of software "Thermocalc".

Organisation

Lecture series supplemented by exercises and homework.
