Material Science I

In general, the lecture "Material Science" (MS1 & MS2) discusses all subdomains of materials sciences starting with physical and chemical basics of matter resp. materials up to the selection of materials, their design-specific application and the characterisation of construction elements. MS1 covers the physical and chemical basics necessary to understand the structure of materials and their properties such as tensile strength, corrosion resistance, hardness, ductility, brittleness and anisotropy. Based on fundamental interactions in solids the structural features and the structure determination by phyicochemical methods will be explained. Major aspects of selected substance classes will be discussed with the focus on the technical relevance in Materials Science and its Structure-Property relations. Topics of the lecture: Introduction: Binding forces in solids 1. Atomic structure of solids (crystal structures, reciprocal lattice, diffraction and spectroscopic techniques) 2. Classes of materials (metals/alloys, compound semiconductors, ceramics, oxides, zeolites, polymers,nanomaterials) 3. Atomic-scale physical Properties of materials(mechanical, thermal, electrical, magneticand optical properties)

At the end of the module Material Science I the students understand the physical and chemical structure of materials on an atomic scale and know methods to examin it. Furthermore, the students are able to identify and characterise the classes of materials that are commonly used in engineering as well as define the different physical properties of materials. They are able to differ the different substance classes in Materials Science and they can classify compounds based on their knowlegde. Students are able to answer questions to the synthesis, reactivity and stabiltiy of materials based on the interconnection between the atomic strucutre odf solids, the chemical bonding and the basic knowlegde in materials chemisty. After visiting the lecture Materials Science I the students are ready to discuss structural features and are able to understand structure (and symmetry)-property relations of solids.

Fundamentals of mathematics, physics and chemistry that are taught in the first and second semester of "Engineering Science": Mathematical basics 1 and 2 (Linear Algebra, Analysis), Experiamental Physics 1 and 2, Chemistry 1 and 2 (Basic chemistry of Inorganic and Organic Materials)

The module consists of a lecture and exercises. The knowledge of the lecture is imparted by talks and presentations. The students should read an accompanying textbook which can be supplemented by additional literature. In the practical, the content of the lecture is demonstrated in practical tests.

The media used in the lecture are: presentations, videos, blackboard sketches.
