The basic understanding of the ideal and real structure of crystalline inorganic materials (metals, ceramics, alloys, solid solutions etc.) and their morphological characteristics of the microstructure (Materials Science and Technology I) so that the relation between structure and macroscopic properties or behaviour (Materials Science and Technology II) can be funadametnally understood.
Final goal is on one hand the ability of choice of the proper material for a certain application, on the other hand the ability to define interference pathways into a materials structure and microstructure in order to tailor its behaviour towards the desired direction (design).
