Course Aim

After completed course the students shall be able to:

* Explain the relation between atom structures, both one- and multiphases, and expected properties obtained in material created by such structures

* Explain the diffusion and it‘s implications and to understand the phenomenon diffusion and make basic diffusion calculations basic diffusion calculations

* Explain and to gauge phase diagram, both the unar, binary and tertial

* Explain the energy- and structure changes related to phasetransformations, nucleations, translations and grain and particle growth

* Explain the casting metallography

* Explain the basic of the mechanical metallography

* Have a basic knowledge of microscopic technology and by using these knowledges be able to characterize and iderntify the microstructure of a material

* To perform laboratory investigations of steel samples prepared and investigated in optical


The course starts with atom structures and crystallography, where the influence and impact of different crystal structures are studied.

After that the conception diffusion is discussed, and the students shall be able to calculate diffusion processes by using the Fick‘s laws in case hardening of steel

The next part is interpretatuion and understanding of the phase diagram where both unar,binary and tertial systems are disussed and examples are given from the iron-carbon system, both steel and cast iron

Next section is the energy- and structure changes and the casting metallography with the focus on phase transformation, grain growth, growth and transformation diagram ( both TTT- and CCT diagram) .Grain and nparticle growth are treated in terms of surface energy.

After that the mechanical metallograhpy is discussed and exemplified by the different hardening mechanisms for a varity of alloys and hardening processes.Elastic and plastic deformation are discussed in terms of basic dislocation theories( edge- and screwdislocations)

The last part in the course is to study optical microscopes where the theories are mixed with a laboratory part in which the students shall study carbon steel with different C-contents and judge the phases and structures present in the samples. Practical sample preparation such as cutting,grinding,polishing,etching and structural determination is also included.

The laboration is based on a low-crbon steel with different carbon contents , which the students shall normalize, harden and temper.Further the students shall study the samples with different carbon contents, nd judge the different structures formed prior and after the heat tratment operations.

An individual laboratory report shall be written and be orally presented for the group and a written report shall be handed


Lectures, industrial lectures, factory visits, laboratory experiments.


Written examination and written and oral presentation of laboratory report.

The course corresponds to MP1037.
